This is my first book by Rob Sinclair and it won't be my last. I was drawn to the story and had to read what would happen next in the next chapter. It was enough twists and turns to keep me guessing until the end. It has the right amount of suspense and tension throughout the story for my enjoyment.
Thank you Rob Sinclair and Bloodhound Books for allowing me to read an advanced copy of Obsession, which I have reviewed honestly and voluntarily

"Obsession" by Rob Sinclair is a gripping thriller that will keep readers on the edge of their seats from beginning to end. The story follows a complex and unpredictable plot, filled with twists and turns that will leave readers guessing until the last page. Sinclair's writing style is engaging, fast-paced, and filled with suspense, making it a compelling read for fans of the genre.

The plot follows protagonist Natasha Simonsen, who had been estranged from her sister Anya many years back and has been battling a relationship crisis in her life following a break-up with her boyfriend. When she learns that her sister has been murdered in Spain and her father is not doing enough to bring the perpetrators to justice, she decides to take the reigns into her own hands and travels to Spain. Natasha reaches Sotogrande in Spain’s Costa Del, a playground for the rich and famous. She begins to wonder how her sister could afford to rent a multi-million-pound property without having a job.

She begins her mission by visiting the police, who are equally baffled by her lifestyle, and informs Natasha that an acquaintance of her sister Anaya, a local drug dealer was also found dead a few days later. Initial investigation by the police revealed that the drug dealer was responsible for Anya’s death, but with his death, the investigation hit a roadblock. In her quest to find out more about her sister’s death, she begins to talk to people staying in and around her sister’s apartment complex. But she kept hitting a brick wall every time she spoke to anyone who knew Anya.

The police revealed to her that there were multiple fingerprints found at the crime scene and all of them had strong alibis at the time of Anya’s murder. She learns that just around the period of her sister’s death, there was a multi-millionaire Arab family, their flamboyant son, and a famous national footballer who resided in the Sotogrande. Natasha begins to trace the life of her sister ever since she reached Spain, and the more she probed, her own life was in danger after being assaulted a few times, threatening her to stay away from the investigation.

Will the police help Natasha to unmask the face of her sister’s killer or will she be disappointed? This was not an easy task. She needed to find out what Anya was doing in Spain and who had the motive to kill her. The plot is narrated in multiple POVs and in different time zones – Summer, when the murder was committed, and Autumn when Natasha begins her investigation.

The characters in "Obsession" are well-developed and multi-dimensional, adding depth to the story and keeping readers invested in their fates. The protagonist is a flawed and relatable character, making it easy for readers to root for them despite their flaws.

Overall, "Obsession" is a thrilling and captivating read that is sure to keep readers hooked until the very end. Rob Sinclair has crafted a masterful thriller that will appeal to fans of the genre and keep them eagerly turning the pages, although I must admit that this is different from the author’s action-packed James Ryer series.

Another wonderful book from Rob Sinclair. Natasha had travelled to Sotogrande in Spains Costa Del Sol to try and do what the police couldn't do, find out who killed her sister there a few months before. Anya was killed in her flat, a multi - million pound rented property. How she could afford to live there without having a job was another mystery the police couldn't solve. The area is a millionaire's paradise and one of the most sought after areas in Europe although with its close proximity to Africa it also attracted drug dealers and gangsters. The police believe that one such gang or drug dealer was involved in Anya's demise although their main suspect was also found killed a short while later. 

Natasha, in her quest to find her sisters killer, kept hitting a brick wall when trying to talk to anyone who knew Anya. The more she probed the more her own life was in danger. Fingerprints belonging to a number of people were found at the murder scene however trying to find out why was proving to be a monumental task. 

This author really knows how to keep his readers in suspense throughout a story and in this case has created a book that is very hard to put down. Moving from the current time back to the summer of the killing offered up more questions than answers. There are red herrings and many twists and turns. A fantastic read!

Thanks to Bloodhound Books for an ARC of this book in exchange for an honest review. A definite 5*

The Prologue of Obsession is a sharp look at the devastating murder that drives this thriller. This riveting story follows Natasha to Spain as she puts her own life in danger to unravel her estranged sister’s murder.

It’s an evenly-paced journey that explores the destructive relationships and emotional trauma of the characters that are entangled in the passionate and deadly web that surrounds Anya. Told through dual timelines and the eyes of different characters, readers slowly sort through the secrets and clues that Natasha discovers.

The author made me feel like I was with Natasha. Weighed down with too many suspects connected to her sister’s hidden life. Not knowing who to trust. I couldn’t quit flipping the pages until the final jaw-dropping reveal!

Sincere thanks to Bloodhound Books and Rob Sinclair for the gifted ARC. All opinions are my own.

🌞 Thank you so much to @bloodhoundbooks for sending me a copy of this book! This was my first read from this author but it won't be my last!

🔎 This has everything a good thriller needs. Plenty of suspense and tension. Several characters who could be the suspect, at least once, I suspected everyone. More and more unanswered questions and quick paced chapters.

🌞 I enjoyed the multi POVS from different characters. As they book goes on you realise how they are all linked. There were also different time zones, from Summer to Autumn. Summer when the murder was committed and Autumn being afterwards.

🔎The last few chapters where fast and so unbelievably tense!! As Natasha discovers more information she ends up putting her own life in danger. You still don't know how to trust right up until the end.

🌞 The ending was a good twist, I wouldn't have guessed it! Overall a really enjoyable read. This would make the perfect summer pool or beach read.

Thank you again to @bloodhoundbooks for sending me a copy of this lovely book. Really enjoyed it and I will be adding more of Rob Sinclairs books to my reading list!

I really love Rob Sinclair's books and this one did not disappoint. Natasha has reached a crisis in her relationship with her boyfriend not long after her sister is murdered in Spain. She is concerned that her father is not doing enough to gain more information from the Spanish Police investigating Anya's death and feels guilty that her sister walked out of all their lives some years ago and that perhaps she should have done more to try and re-establish contact. Natasha decides to fly out to Sotogrande, a playground for the rich. Here she finds more questions than answers as it seems that Anya knew a number of people who lived in the area or were on holiday. But how did Anya manage to afford a luxury apartment in this expensive resort and who knows more about Anya than they are letting on? Obsession is a dark and twisty thriller that had me hooked! Thanks to Bloodhound Books for an ARC of this book.

An outstanding fast-paced novel.

I’ve had the privilege to read all Rob Sinclair’s books and love his style. Then this novel arrived! (Possibly) A stand-alone written in the voice of Natasha Simonsen. She is unimpressed with the police in Malaga who don’t seem to be any closer to apprehending her sister, Anya’s, murderer.

It’s not going to be straightforward. She’ll need to discover what Anya was doing in Malaga and who had reason to kill her.

We hear from other characters and discover that nothing is straightforward amongst the very wealthy residents who mixed with Anya.

An excellent read. Very different in style to Rob Sinclair’s previous books and that’s what is so refreshing. Rob Sinclair has managed to pull off something that few authors can do – which is change direction. The characters were well drawn. The story flowed perfectly and the subject was interesting.

This is another very moreish read from Rob Sinclair. I'm used to his action packed James Ryker series and this book is very different. Natasha wants to find out the truth behind her sisters death and goes to Sotogrande to search for answers. The authors writing is very good here, I actually didn't like or care for most of the characters and yet found it hard to put this book down and would return to it whenever I could. I really liked the dual time lines which moved from past to present easily, and that the story was told through the different characters which, for me, added so much suspense, intrigue and depth. The plot line is very believable and well thought out and went off in unexpected ways so many times which threw me off and had me guessing and eager to know what would happen next. Overall a great read and one I'd recommend.

Thank you Bloodhound books for my ARC. This was my first book from Sinclair. It will not be my last.I truly enjoyed this twisty thriller about a sisters quest to discover what happened to her sister. Anya was murdered in a tropical paradise. Her sister, Natasha from whom she was estranged, decided to take up the investigation since the police were getting nowhere. She soon discovered there was a lot she did not know about her sister or the people she associated with. First, was how could she afford the flat in which she resided without a job? As Natasha connects with the people who knew Anya she finds herself in danger. Yet this does not stop her. Multiple acquaintances seem to have motive. Many had been inside Anya's flat. When you think you figured out who the killer is, guess again.

I really liked reading this thrilling and action packed psychological thriller by Rob Sinclair. I’ve never read novels by the author but after finishing this novel I’m certain that I will be seeking out this author in the future to read more by him.
This thriller ticked all the boxes for me and kept me guessing right until the end of who the culprit was and I would have never guessed it. I loved the luxurious Spanish setting as well as England as a setting. I liked the main characters and the chase for the killer.
This novel gripped my attention and interest from the very start and held it right until the end. I’m giving this thriller 5 stars as I really loved reading it. I think other fans of thrillers will like it too.

I enjoyed reading this suspenseful story. This is an author that I have enjoyed from the first book I picked by him and this one is no different. I enjoy his writing skills as well as his attention to details that make his stories realistic. This is a well written story that has twists and turns that you won't see coming. They had me sitting on the edge of my seat just waiting to see what would happen next. I enjoyed how the characters pulled me into their world from the beginning. They are connectable, strong and supportive of each other. I enjoyed watching their growth as well as had me guessing on what would happen next. This is a story you don't want to miss. I highly recommend this book and this author.

This story comes out May 10th of 2023, the paperbacks is available April 26th of 2023. Natasha and Anya are two years apart. Anya is older than Natasha. Natasha Simonsen's, she had photographic memories. especially when she hears Anya her older sister been found murdered. Their mother passed away from cancer and they become distant from each other as well as their cheating dad. This is a gripping, compelling and interesting novel. As a reader's I enjoyed the characters in the covers of this book.

Action-packed investigative thriller – Natasha decides to investigate her sister’s death after the Spanish police fail to even have a solid suspect. Told through a dual timeline, lives unravel and unexpected secrets come to light, some of which are hard for Natasha to hear. It is a little far-fetched and has too many threads at one point, but still an enjoyable read.

Rob Sinclair writes in a way that makes you feel you are right next to the characters, living with them the events that happens in the book, and is all because his attention to details, so much so in the case of this book that he leaves, very cleverly, lots of hints and clues as who the killer is, but doing it in a way that the reader don't grasps the identity until it is presented at the end of the book.
However, for me the reveal of the killer and what happens in that scene felt a little rush and very much getting the characters out of the way.
Is the final scene of the book suggesting that they may be a sequel to the book?

I’ve read some of Rob Sinclair’s books before and this one was slightly different and a great read. Natasha is looking for answers after her sister’s death in Spain. She travels out there to see if she can find information that the police haven’t been able to. She flies to Sotogrande and finds that some people do not like her asking questions, her life could also be in danger. An excellent thriller with lots of twists and turns.

Dark, plenty of twists and I really hadn't worked out "whodunnit" or why. I felt I'd have liked some introduction to Anya herself and why she ended up in Sotogrande doing what she was. Obsession was the perfect title - everyone was obsessed with something. I thought the individual stories were great in laying red herrings. A good read, but it did take me longer to plough through it than anticipated so it didn't keep me completely hooked. #obsession #bloodhoundbooks

Thanks to bloodhound books for this arc copy, and my review is my own. How far would you go to find who killed your long-lost sister? Anya moved to Spain and just ditched her family. After Anya gets killed and family finds out, and now her sister wants justice after the investigation through the police goes nowhere. Who killed Anya and why? This book is a page turner, and I really enjoyed it.

A page turner. A thriller with a lot of twists and turns. It took a while to get to know so many characters, but as the story progressed, their part all made sense.
Obsession is Natasha's quest to find her sister's killer/s and the reason behind it.
My first book by the Author and definitely a gripping tale.

Natasha's sister Anya has been murdered in Spain, with nobody arrested for the crime. Natasha is determined to find out what happened to her sister - but realises how little she knew her, & how much danger she is putting herself in. A typically gripping thriller by Rob Sinclair, I really enjoyed the alternating timelines as Natasha struggles to reach the truth.

A standalone from from the author this time which sees a sister out in Spain trying to get the bottom of her sister's death there. As usual from Mr Sinclair, there are lots of decoys and misdirection to confuse the reader as to who the guilty party is. A great page turner as you want to find out who is actually the killer.

A fast paced thriller with lots of twists and turns and multiple points of view is the brief way to explain this book. The characters were well written and developed enough to keep my attention on the plot and how the relationships between them as the murderer is being sought intrigued me. I voluntarily reviewed an advance readers copy of this book.

Engaging at times but a poor ending

Obsession can certainly pull you in and keep you engrossed, but the numerous questionable passages and especially the ending were just not in any way believable. Also, way too many missing words and grammatical errors - a much better editing job is definitely needed!
