The second book in the Ryker Returns series is a nail-biting and fast-paced thriller by Rob Sinclair that could also be read as a stand-alone. After reading the first book in this series - Renegade, I was keen to know what the author has in store for his fans. Truly this was no disappointment with lots of action and twists and turns along the way. The book opens with James Ryker leading a team of seven JIA operatives on a covert mission in Qatar, where they are to assassinate Pavel Grichenko, a Russian Oligarch and a Kremlin loyalist, involved in arms sale to terrorists, funding rebel movements, shady drug dealings and human trafficking. Though the operation did not go as per plan, Ryker was assured by his team that Grichenko is killed. Ten years later, after Ryker broke off all ties with the JIA and while spending time in Prague, he is aghast with the news of the murder of Pavel Grichenko and his wife in Cotswold, England. Ryker is flummoxed and curious to know what happened on that fateful night ten years ago. Had someone from his team helped Grichenko escape? He was convinced one of his teammates had betrayed. But Who and Why? Ryker needed answers and sets out to track his team members. Meanwhile, a female assassin is on the prowl, who is alleged to have killed Grichenko is now hunting down the members of Ryker's team. Ryker needs to act quickly if he has to get the answers before they are killed. Ryker trusts no one and time is short. Will he be able to save his mates? Will he find the betrayer from the ten-year-old operation? What was his motive? Who was behind the master plan? Most importantly, who was the female assassin, and will she kill all of them. Reading through this book was very much like being on a scary and unpredictable roller coaster, with more ups and downs that you can find on a board game. The authors writing skill engineers enough surprises and the suspense is not revealed until the action-packed finale. In all, an exciting and mesmerizing thriller with subterfuge that makes it a compulsive read for espionage fans. Hope the next book in the series will be as exciting as the two releases so far.
