#1 Hot New Release

In the battle between faith and science, you don’t have to choose a side.


The rift between faith and science seems to grow larger by the day, as many view the modes of thinking in opposition to one another. People often feel forced to choose between the two, with no apparent way of reconciling them. However, the experience of wonder might just hold the key that brings these two seemingly contradictory sides back together.



In The Call of Wonder, Brian Cranley expertly guides you on a journey through philosophy, theology, cosmology, and biology, where you will discover how science can be a revelation of God all its own. Using fictional elements combined with time-tested wisdom and historical facts, this book challenges you to rethink how you view modern scientific discoveries—like the Big Bang, life’s evolution, and the human mind—in light of ancient descriptions of a rational God.



The Call of Wonder is a fascinating exploration into the connections between God and science that have been present since the very beginning of time. Cranley’s expertise in these diverse fields will help you uncover a new and powerful perspective on how faith and science are two sides of the same truth.

This book is very intriguing as little fables lead into important topics of science and faith. Many people think these two are opposed to each other and you have to sacrifice one for the other. Brian Cranley does a really good job at trying to close the gap. I believe this book is great for discussion between people who hold truth as their goal, no matter where it takes them. I feel like there is more to come from this author and he has more to say. Looking forward to it.

As a PhD scientist and a Christian I'm always very interested in the combination of faith and science and how others find that balance. The description of Cranley's book intrigued me because it seemed like he would take a tour of different fields and see how God and science can exist together. However, the description of the book was not fully accurate.

Cranley talks about the 'God of reason' and other Christian concepts in the book description, but in reading the book his overall focus is more on monotheism with brief asides into Judaism, Christianity, and Islam. It felt like false marketing to go into this book thinking it was from a Christian perspective and it was not. The last chapter of the book Cranley makes a case for why he believes in Christianity, but it feels like an aside. The book was also heavily philosophical which I did not expect and it detracted from the Cranley extrapolating on science and religion.

Throughout the book, Cranley presents science first and monotheism second which indicates he's interpreting monotheism through the lens of science. It doesn't feel as much that God created science than science informs how we think about God. Cranley also makes a lot of strong statements that make it sound like he's an authority in all of the fields he talks about when he isn't an authority in biology, cosmology, and philosophy.

Overall, I was disappointed with this book and its misleading advertising. If the description had been followed and more acknowledgement included of Cranley's expertise areas versus those he was speculating on I would have enjoyed it more.

Thank you to Netgalley and the publisher for the eARC.

When I was first introduced to The Call of Wonder: How the God of Reason Created Science in His Image, I was immediately intrigued and eager to dive in. The title and also the subtitle caught my attention because I think all of us, or at least most of us, at one point or another, wrestle with the same question this book explores: how do faith, religion, and science fit together?

Brian Cranley approaches these questions with the balance of a scientist’s mind and a believer’s heart (and mind too). He’s well qualified and educated in the sciences as well as theology. And he writes with humility and curiosity rather than certainty or dogma. I appreciate how rather than taking a specific stance, I feel like this book is designed to open a conversation.

I enjoyed how the book is structured. Chapters begin with short, fable-like story that set the stage for deeper exploration. These short narratives are creative and inviting and give you something to reflect on before he connects them to philosophy, theology, or a particular scientific concept. It makes you think and also helps bridge the topics.

The author’s writing is very accessible and enjoyable to read. I liked how he weaves together references to classic and modern works some I’ve heard of, others I probably never would have encountered on my own. Like Brian Johnson , author of Areté: Activate Your Heroic Potential, he draws wisdom from a wide range of sources, distilling complex ideas into clear, understandable insights. I found myself highlighting many passages, jotting a lot of notes, and pausing often to think and re read more than a few chapters.

A great example of the author's ability to take dense and complex subjects and make them accessible is the way he distilled thousands of years of religious development into a simple chronological timeline of major movements in worship. This basic approach allowed me to visualize the broader arc of humanity’s relationship with God (or gods) as I had never seen before.

I also truly appreciated that the author discloses his faith yet doesn’t push a specific agenda. Instead, he invites one to think and consider that harmony can exist between faith and science. And he also demonstrates genuine curiosity and has an open mind.. He suggests that wonder itself, that deep sense of amazement of the universe and our place in it, might be the bridge between reason and belief.

I’ll be recommending The Call of Wonder to a lot of friends and family members, many of whom I have had past discussions on spirituality, religion and the mysteries(and miracles) that surround us.

The book lives up to it's title as it truly is wonderful.

Brian Cranley’s The Call of Wonder is a remarkable achievement. It’s an elegant and deeply engaging synthesis of philosophy, theology, and science that manages to be both intellectually rich and entirely accessible to readers, like myself, without formal training in those fields.

What impressed me most was how Cranley distilled such a vast sweep of human thought, from the origins of life and the universe to the development of reason, ethics, and belief, into a narrative that is clear, compelling, and often awe-inspiring. He weaves together topics like evolution, cosmology, the concept of LUCA (the Last Universal Common Ancestor), The Big Bang, The unmoved mover, and the philosophical implications of form, space and time with extraordinary clarity and a masterful simplicity

The book unfolds like a guided journey through the most influential ideas that have shaped how we understand the world and our place in it. It’s as if you’re exploring the essence of theology, philosophy, and science all at once but diving straight into the core insights, without getting lost in unnecessary complexity.

Cranley thoughtfully examines how the most profound questions of science and faith may not be at odds, but instead offer complementary paths to understanding. He skillfully unpacks centuries of thought, religious tradition, scientific discovery, and human inquiry, weaving them into a coherent and inspiring narrative. Whether you’re deeply familiar with these subjects or just beginning your exploration, The Call of Wonder will leave you with a renewed sense of curiosity and a deeper appreciation for both God and the natural world.

Highly recommend.

This beautifully written exploration of faith and science demonstrates how reason and revelation can work in harmony rather than opposition. The author's deep love for both God and the natural world shines through every page, creating an accessible work that bridges ancient wisdom with modern scientific wonder.

What sets this book apart is its ability to weave together insights from classical philosophers and theologians without becoming overly academic. The writing is clear and engaging, making complex theological and scientific concepts understandable to general readers. The author skillfully shows how scientific discovery, rather than diminishing faith, can actually deepen our sense of awe and point us toward the Creator behind the cosmos.

The heart of the work lies in its demonstration that the physical world's intricate beauty and order reveal something profound about its divine origin. This isn't a defensive apologetic but rather a joyful celebration of how faith and reason illuminate each other.

I thoroughly enjoyed this thoughtful and inspiring read. It's a perfect book for anyone interested in exploring how science and faith can enrich rather than threaten one another.

Okay so I don’t usually read books like this, I’m more into novels and stories, but this one kept
popping up for me so I gave it a shot. Honestly? It surprised me a lot. At first I thought “oh here
we go, another religion vs science fight” but it’s not that at all. Brian talks like someone who’s
lived both sides, the science side and the faith side, and he doesn’t force you to pick. The
mountain climbing story in the beginning made me feel like I was right there, struggling up the
rocks and then seeing the view at the top, and it tied so perfectly to the idea of wonder. Some
parts got pretty deep with Plato and Aquinas and all those names, but he explains it in normal
language. I stopped a few times just to think about my own beliefs, and I don’t usually do that
with books. Glad I picked this one up.

I wasn’t sure about this book when I bought it. The title sounded kind of lofty. But wow, it really
drew me in. The introduction with the yard signs Love is Love, Science is Real, etc. that
hooked me, because I’ve seen those exact signs and wondered the same thing. Who are they
talking to? From there, Brian takes you on his own journey from engineering to theology, and
you can tell it’s personal, not just theory. By the time I got to the chapters about Plato and
Aristotle, I felt like I was learning but also just listening to a story. This isn’t a book you rush
through, it’s one you sit with.

So here’s the deal, I wanted a book that talked about God but didn’t make me feel dumb for
liking science. This did it. It’s not perfect, sometimes it felt a little too much history lesson for me,
but I get why he included it. It builds the case. What stood out for me is that Brian doesn’t act
like he has all the answers. He admits his own struggles, how he went back and forth between
belief and doubt, science and church, and that made it feel more real to me. I didn’t agree with
everything, but it definitely stretched me.

This book is long, but worth it. I read a little every night and honestly looked forward to it. The
whole part about authentic wonder hit me hard. Like yeah, I waste time scrolling videos, quick
dopamine hits, but when he talked about his kids looking at otters at the zoo or watching a lunar
eclipse, I was like… yep. That’s what real wonder is. I needed that reminder. The science stuff
(Big Bang, evolution, the human mind) was laid out in a way that didn’t feel like a lecture. More
like, here’s why this matters. And then he connects it to God without being pushy. It’s rare.

Man, I loved this book. It’s not like anything I’ve read before. It talks about God in a way that
makes sense with science, which is usually where I check out. The fables at the start of each
chapter were cool too, like a mini story that sets the mood, then he goes into the heavy stuff.
Honestly I thought I would skim those, but they ended up being some of my favorite parts. I felt
like he was taking me into another world and then back to reality. Made the philosophy stick.

The writing style is smooth but sometimes almost too smooth, like I’d be halfway through a
chapter and realize I was nodding along but not sure I fully understood. That said, the overall
message is powerful: faith and science don’t have to fight. I loved the way he explained wonder
as the thing that ties them together. I’ve been a Christian my whole life but always felt guilty for
loving science documentaries. Now I don’t. That alone was worth it.

This book took me on journey through science, philosophy and God. Instead of picking a side it wove them together. There were plenty of times when I set the book down to contemplate. The author’s knowledge on these matters is impressive and easy to follow.

Loved this book!

"The Call of Wonder" does not try to tell you what to do but encourages you to be mindful of the things around you and appreciate them. The author creates a light-hearted, easy-to-read book that will inspire readers to spend some time in reflection and to feel grateful for their lives and everything that surrounds them. The author's stories, questions, and reflections allow readers to take time away from their hectic lives and reflect on what is happening around them and appreciate the wonder of living in this world. This is a book that is easy to read, but it will cause you to think about the importance of taking time to enjoy the little things and enjoy life. This book is an excellent choice for readers who are feeling stuck in a monotonous routine and want to feel that spark of wonder again.

Excellent research on history of multiple scientific discoveries and religions that were essential to the book’s claim. As a reader who enjoys multiple genres, the fable each chapter starts with helped guide your understanding. It’s definitely a book you could use for a literary circle, or helping you continue researching deeper into areas of science and religion.

Great Balance

I consider myself a spiritual and Catholic person, and this book truly surprised me and deeply caught my attention, as it manages to reconcile science with faith and reason in a very authentic way, without placing them in opposition. On the contrary, it shows how they can coexist and complement each other naturally.

The book also gives science its rightful place while valuing creativity, natural development, and human imagination. This is especially meaningful in times like today, when everything seems to require constant proof and strict methods. At the same time, it highlights the importance of individual freedom and personal expression.

This book turned out to be very interesting, enriching, and highly recommended for anyone seeking a broader and more integrated view of faith, reason, and knowledge.

Very interesting approach

I really enjoyed reading this book by Brian Cranley. This was my first time reading this author, and I really enjoyed the experience. His writing is clear, calm and thoughtful, which makes complex ideas feel approachable and easy to follow.
One chapter that stood out to me was the reflection around the Big Bang and the idea of wonder, since it connects science and meaning in a very accessible way. I consider myself a very spiritual person, and I think he manages to combine science and faith in a very interesting way.
The format invites you to slow down and think, rather than rush through the pages. I found myself reading with curiosity and genuine interest. I would definitely recommend this book because it offers a fresh perspective and encourages open and deeper reflection.

Looking at the world with wonder

While reading this book, I felt an invitation to slow down and observe reality with more calm. Many times, we believe that science answers everything and that faith belongs only to personal beliefs, but this book suggests something different, that both are born from the same sense of wonder. It made me think about how understanding the world better does not remove mystery, but often deepens it. Reason does not weaken curiosity, instead it helps it grow. The book also made me question the idea that rational thinking separates us from the spiritual. Perhaps the opposite happens. When reason is used with honesty, we learn to value what we cannot fully control or understand. This book reminded me that asking questions remains one of the most human ways to move closer to truth.

Breaking paradigms

In The Call of Wonder, author Cranley, in a clear, simple, and direct way, prompts us to reflect on one of the longest-standing and most common debates, one that has persisted for years: the opposition between science and faith.
The author presents a possible solution to this situation: through wonder, these two disciplines (science and faith) can interact and support each other for a better understanding of certain topics.
As the reader progresses, they come to understand that through theology, biology, philosophy, and cosmology, science can be viewed as a revelation from God.
Ultimately, this book can be considered a work that breaks with many of the paradigms we all held about the relationship between science and faith.

I was provided with a free ARC by NetGalley in exchange of an honest review of the book.

This book centered a lot more around philosophy than I expected. I have never viewed this topic from a philosophical perspective and found this very interesting.
The part that centered around science were well done and understandable for those, who have no experience with the topic. I would have wished the author to go more into depth for some topics.
The fables at the beginning of each chapter were not necessary for me personally, but I think a lot of readers will enjoy them. They certainly break up the non-fiction topics and give a short break between more theoretical descriptions.
I also enjoyed the quick nod to Project Hail Mary by Andy Weir.

The Call of Wonder is a book that invites readers to bridge two conflicting worlds: faith and science. Drawing from his unique background in both biomedical engineering and philosophy, Brian Cranley shows readers that reason and belief are not rivals; instead, they are partners in our pursuit of truth. In this book, you'll find Cranley's honest reflections on doubt, reason, and belief, which remind readers that questions are not threats to faith but pathways into deeper wonder. For more information, read The Call of Wonder by Brian Cranley.

Firstly, The Call of Wonder is a thought-provoking book that explores the relationship between science and faith. The book is crafted through the personal lens of an individual who has deeply journeyed through both realms. The author was once a biomedical engineer and is now a student of philosophy and theology. So this book, I have found, invites the logic of the laboratory and the mystery of divine revelation.

The aim of this book is to reconcile the seeming divide between scientific discovery and religious belief. These domains could easily become antagonistic, but the author's argument became complementary pathways to understand a shared truth. This idea is not presented as an abstract theory but rather as a deeply personal conviction born of years spent in both scientific and spiritual disciplines.

A major theme that I believe was present throughout the book is the pursuit of what the author calls "authentic wonder". Unlike fleeting excitement from entertainment or ungrounded fantasies, authentic wonder arises when we encounter realities far greater than ourselves; be it the vastness of space, the elegance of nature, or the idea of a timeless creator. Such wonder does not merely entertain; it transforms, humbles, and anchors us.

One of my favourite aspects is the fact that the book is inclusive. The author's respect for diverse perspectives draws in religions such as Christianity, Judaism, Islam, and even non-religious worldviews. The author constructs a broad and inviting foundation for anyone sincerely seeking truth. The fact that he acknowledges the contribution of multiple traditions makes this work more than just a Christian apologetic; it becomes a universal reflection on human longing for meaning, awe, and understanding.

Furthermore, I enjoyed this book. The Call of Wonder is more than a book, it is an invitation. It doesn't matter if you're someone who trusts science but questions religion, or someone who believes in God but is unsure of science, this book gently calls you to listen again. There were also no noticeable errors in this book; it was professionally edited. Therefore, I rate The Call of Wonder 5 out of 5 stars.

I recommend this book to curious and open-minded readers who are interested in seeing that faith and science are not enemies; they are partners in the search for truth. So, if you’ve ever wondered how the universe began, what your faith really means, or whether science cancels out God, this book gives you a fresh, balanced way to explore those questions.

THE CALL OF WONDER by Brian Cranley
The premise of this great book is that if we believe God created the Universe, then modern scientific knowledge should lead us closer and closer to God. Brian takes us back to the philosophers and theologians of old in the Greek, Jewish, Christian and Muslim traditions to show us how modern science is slowly confirming the exact same understanding of the characteristics of God that we received from the great minds of the past.
The book starts in Ancient Greece and introduces us through an imaginary guide, Sophia, to Plato, Aristotle, Aquinas, Augustine, Galileo, Darwin, Einstein, Hubble and others on a tour of the earth and the planets. Brian starts with the great philosophers, theologians and scientists of old and takes us through to the modern science of physics, geology, biology and quantum mechanics to the very first second of the Big Bang at the beginning of time, matter, energy and space. An incredible journey of wonder!
This Way of Wonder calls to those who have left their Faith behind as they grew in modern scientific knowledge, showing how the conclusions of Theology and Science are coming together into greater and greater alignment. We can love our Faith and our Science without contradiction, we can embrace them both. It seems like the Holy Spirit is moving modern man back to their Faith foundation even as they explore the outer wonders of God’s universe. I love the book and have come away a better Christian by reading it as I marvel just how great is our God as seen in the greatness of His creation. As Scripture says “For from the greatness and the beauty of created things, their original author, by analogy, is seen.” (Wis. 13:5) A great journey Brian, thanks!

Two sides of the same reality – The wonder of unity!

Texas author Brian Cranley combines his BS from Texas A&M in biomedical engineering with his Masters in Divinity from University of St. Thomas in his respected medical device business, now offering his thoughts on the impact of science and spirituality in this his initial book. Introducing each section of discussion Brian opens with a ‘fable’ – an extremely entertaining and informative format for blending his thoughts with his admirable gift for storytelling! As he states early on, ‘In this book I hope to join the centuries-old discussion of how a rational belief in God can coexist with a love for scientific discovery.’

An example of his clever use of fables, the initial congregation results in the following questions: ‘What on earth does Greek philosophy have in common with Einstein’s theory of relativity and outer space? And how will Charles Darwin comment on the nature of divinity that the three groups of theologians presented so passionately?’ Thus opens his survey of science as divine revelation, an invitation to rediscover the roots of ancient wisdom, philosophy, cosmology, and biology. In this manner Brian leads the richly integration of faith and science coming together, sharing memorable phrases such as ‘God has written His image into the very science of the universe.’ A most welcome book, especially at this time of questioning everything!

Book Review: Call of the Wonder by Brian Cranley

Call of the Wonder is an extraordinary debut by Brian Cranley — a deeply insightful and thought-provoking exploration of faith, reason, and the human search for meaning. Cranley does a remarkable job tracing the history and evolution of theology and religion, weaving together philosophical reflection with a clear understanding of how belief systems have shaped, and been shaped by, human progress.

What stands out most is his balanced and intelligent discussion of how science and religion can not only coexist but also complement one another. Cranley challenges readers to think critically without dismissing either side, offering fresh perspectives that feel both intellectually rigorous and spiritually resonant.

It’s rare to find a first-time author with such a strong grasp of complex ideas and the ability to make them accessible and engaging. Call of the Wonder is easily one of the most thought-provoking and rewarding reads I’ve had this year. Congratulations to Brian Cranley on an amazing first work — a book that invites reflection long after the final page.

This book has been a mind-blowing discovery and reading. Throughout my life, I have been a religious person but sometimes doubt comes to my mind because when you think about science, and other facts that are away from religion, or that you think are distant makes you doubt about where your faith is. And this book has changed has convinced me that these 2 sides are closer to each other than I could ever have imagined before. This book awakened my curiosity and has connected faith, reason, and science in an amazing way and with an incredible message. The way it is written is thoughtful, making you reflect on this. The examples given in this book, such as early scientists and historical moments where faith and reason worked together, are great arguments on how to reframe science as an act of curiosity based on meaning and not just information and data. This book has strengthened my relationship with God and encouraged me to have a thoughtful curiosity.

When I finished The Call of Wonder by Cranley, I was surprised by how much it stayed in my mind. I thought it would be very heavy or too religious, but it was actually easy to read and interesting.

What I liked most was how the book explains that early scientists believed the world had order and rules because they believed in a rational God. That helped me understand why people felt confident studying nature instead of being afraid of it. I had never thought about science starting from faith in that way before.

One part that really stayed with me was the idea of human responsibility toward nature. The book made me reflect on my own habits, like wasting resources or not thinking about the impact of my choices. It reminded me that if nature has meaning and order, then we should treat it with respect, not just use it without care.

The Call of Wonder is a refreshing and thought-provoking journey that bridges the often-divisive gap between science and faith. Brian Cranley invites us to see the divine through the lens of science. This book blends theology, philosophy, and science with a unique voice that’s intellectual and heartfelt.

Cranley’s exploration of cosmology and biology is accessible yet deep, making you stop and reflect on the beauty and reason woven into the universe. Fictional elements are tastefully used to illustrate timeless truths, giving the book a narrative pulse.

If you’ve ever wrestled with reconciling belief in God with the logic of science, this book feels like a gentle but firm answer. It encourages wonder, not dogma and that’s its greatest strength. A powerful, unifying read for seekers, skeptics, and believers alike.

I’ve always kept science and faith in separate corners of my mind, so I was genuinely curious when I picked up The Call of Wonder. Brian Cranley explores how both might actually be pointing to the same truth.

The first half leans heavily into ancient philosophy, think Plato, Aristotle, which at times felt dense but gave helpful context. The second half, where Cranley brings in the Big Bang, evolution, and even Scripture, felt a bit rushed in comparison, but still left me with new questions and perspectives.

I find the book not really answer the "how the God of reason created science in his image" but a good starting book to explore about the ideas.

The Call of Wonder is the perfect book for you if you have ever wondered whether God and science can coexist. I love the way that the author has structured this book, starting each new chapter with a fascinating fable. These introductory fables allow the reader to reflect before reading on. It is also wonderful that Brian Cranley has shared his extensive knowledge on cosmology, philosophy, biology and of course, theology. He does so in a clear and honest manner without being overbearing in any way. He lets the reader make up their own mind, while showing that the wonder of creation might be the answer to reconciliation between science and a belief in God.

What I love about The Call of Wonder is that it never tries to convert or convince it simply invites. It’s about seeing everything, from the stars to your own thoughts, as part of something greater. I read it slowly, like one chapter a night, and it honestly changed the pace of my whole week. When I reached the end, I texted Linda and said, “Okay, you were right. This book really is a journey.
