Scatter. Jackson Traine, #2

He swore off time travel to rebuild his mental health. But he finally found out who took his brother and playing it safe is no longer an option. In the nine months since his run-in with the Demon Monks gang, psychologist Jackson Traine has been learning combat skills while using non-time-travel resources to hunt for his brother. It's reduced his PTSD symptoms, but seriously hurt his relationship with the love of his life, Dr.
Lena Cortland. Then a series of discoveries and violent encounters unveils the group that's holding his brother. And it's clear they not only know about Jackson's ability to jump back through time, they want to abduct and use him like they've been using Kenny. Fighting gangsters was one thing. How is Jackson supposed to fight a sophisticated enemy that can turn his own power against him? Scatter is the second book in the fast-paced Jackson Traine science fiction thriller series.
If you like determined protagonists, relatable internal struggles, and harrowing choices, then you'll love Terry Hayman's smart, pulse-pounding tale. Buy Scatter for time travel like you've never seen it before!  "When a new ally appears-offering to help locate his siblings-Jackson realizes he may have made a pact with a devil greater that all his enemies combined, one who is a threat to his mental health and his fraught relationship with Lena.
The advice to 'Know as much as you can about your commanders and what they want from you' never felt more essential. Hayman deftly mixes the engrossing, geeky intricacies of the science behind time travel, paradoxes, and alternative timelines with an ingenious, fast-paced plot . Smart and powerful female characters and the moral dilemmas of time traveling and changing the timeline enrich a narrative that ends with a strong setup for the next volume.
A fun and clever time-traveling tale."  --Kirkus Reviews "I give Scatter by Terry Hayman 5 out of 5 stars. Reading this book, I felt like I had entered into an in-depth discussion on quantum physics. Not to mention all the excitement that occurs as Jackson is abducted, assaulted, and drugged. How would you feel if you realized that there really are multiple timelines in which another you exists?"   --Reedsy Review
