Soul Siege is an excellent addition to the Landon Walker Series. I know I’ve said this before, but I truly believe that each new book in the series gets better. Soul Siege is clear proof of that. Right now, it might even be my favorite. After finishing this book, I’m eager to see what the next one will bring.

From the very first page, Soul Siege grabbed my attention and kept it until the very end, and even now, I’m still hooked. I really enjoyed this book because it was both exciting and thought-provoking.

One day, a man named Caleb Mercer shows up unexpectedly in Blue Springs, just like Landon did before him. Caleb says he’s a healer. Landon isn’t sure, but he’s determined to find out the truth. He hears about a gathering and asks Sarah to help him investigate a man who says he can work miracles.

Landon seeks the truth and helps others find it. He holds Bible study sessions at the library where he works. He encourages his students to look for answers on their own by exploring their surroundings.

Soul Siege is a fast-paced read that will definitely keep you busy for a few hours. Pick up a copy today and follow Landon on his search for the truth.

Landon feels betrayed when he hears of another young man, with healing powers, who suffered from the same amnesia that he had, and he starts to doubt his worth, then he hears demon voices in his head doing their best to bring him down. He and Sarah decide it is time to visit the healer during one of his healing services, and what Landon discovers is much more than he ever expected. Caleb is his split image, and he was being called 'the vessel', and treated more like a prisoner than a healer. He was being 'protected' by a whole group of armed people, trained to keep people away from him. Landon feels that Caleb is in danger, and decides to intervene especially after Vanessa does her research and what they discover really shatters him. But through all of this his faith never wavers, knowing that he is the light to fight the darkness once again encroaching on their lives. I do believe this was my favourite book in the series so far, and I found it to be very thrilling and a page turner which I could not put down. I am looking forward to the next book as the plot is thickening with new factors arising and new characters appearing in the series.

Landon is feeling a little bit lost, he no longer has the ability to heal others. He feels abandoned by his guardian Angel. He starts hearing a voice in his head telling him he was unworthy and that he had been replaced by someone who was more worthy. Then he hears about a young man in Blue Springs whose story is the same as his, no memory of his past. The young man called Caleb is healing people like Landon used to. Is he genuine or a fake. Landon and the rest of the gang, Sarah, Zacharias and Father Sciplini head to Blue Springs to see for themselves what is going on there. What Landon finds is a young man who looks so much like him its uncanny. Caleb is surrounded by "security" but to Landon it looks more like he is being held captive. When they get back to KU they start digging into Calebs details, Vanessa digs deep and discovers that Landon and Caleb are actually brothers separated at a very young age and put into different foster systems. Files altered for some reason. Landon decides he has to go back and talk with Caleb. An excellent read.

Ive enjoyed this book so much, cant wait to read the next book.

"Soul Siege" stands out as a remarkable addition to the Landon Walker Series. I mentioned it previously, but I genuinely believe that each installment in this series surpasses the last, and "Soul Siege" exemplifies this. At present, it may even be my favorite. Landen becomes increasingly relatable as his personal struggles resonate deeply with me. The revelation that he has a brother was unexpected and added a delightful twist. The author continues to introduce surprising elements that compel me to keep reading. After completing this book, I am eager to discover what the next installment will unveil. The author has become one of my favorite authors.

From the very first page, "Soul Siege" captivated my attention and maintained it until the conclusion; even now, I remain thoroughly engaged. I thoroughly enjoyed this book, as it offered both excitement and thought-provoking themes.

Good fast paced story. With relateable characters. Who have faults. Learning to follow after christ. Can't wait for next book in series to see how this ends. Learned a bit more about the mysterious Landon. A bit more of his past. As he learns more about himself. He also learns more about his relationship with God.

We are loved for being us. Not for what we can do. Even if we lost all our talents God would still love us.

Even those in the middle of spiritual warfare can't always see anything beyond the physical level. All is well at Kansas University. At Blue Springs, though, something new has just started. What is going on? Why does Landon feel so drawn? Landon, Sarah, Zacharias, Father Sciplini, and Vanessa investigate and learn more about Landon's past.

Be prepared for a bit of a tease: there is definitely more to come!

Makes you think
When Landon hears that there is someone named Caleb healing people in Jesus' name he has a spiritual crisis of confidence. This is a story of how what has happened in the past is leading to a new path in his spiritual journey. You feel as if you are moving right along with him. The spiritual insight presented in the story can be beneficial to your own spiritual journey. This book as with the rest of the series are enlightening and hard to put down once started.
