A true thriller. Sci-fi even for those who don‘t enjoy sci-fi—heck, even for the most reluctant readers! Trust me, Crouch will win you over. It has you stuck on “what if‘s”, it pulls at emotions. The characters are constructed well; the plot—fantastic. Even with a non-linear timeline (jumps back and forth and sideways), coupled with two different perspectives—I never felt lost, which can be a source of frustration in books akin to this. AWESOME.
