Ok, I'll admit the premise sounds fun. BUT, I read a snippet and its BULLSHIT that the Feds would expect them to adopt an undercover impersonation of a REAL person OVERNIGHT! Let alone a gay couple because any slip-up could get them killed and I don't think many straight guys (as they're thought to be) could pull this off. So that flimsy aspect is annoying.
Spoiler for book 2: Oh, and Ty's fucking HAND being BITTEN by a MOUNTAIN LION would NOT be completely healed in three weeks. No way.
