I really enjoyed the premises of this book! I love science thrillers and thus was very excited to read this! The execution of the book didn't quite hit the mark for me. The characters were so-so. I really enjoyed the biological aspect to the plot of increasing longevity though. Overall, it was a pretty good book.

This novel was a terrific read! I enjoyed every page. The plot was complex, suspenseful and intense. It’s one of those books you can’t put down until the end. Great book with a great ending. Full of twists and turns you won’t see coming! I highly recommend this book. ARC provided by publisher via Netgalley in exchange for an honest review.
