4.5 stars 
 Finally! A gem of a book after so many duds lately. I loved the witty banter, believable chemistry between these characters, and Bowen gave us a blushing hero! I am a sucker for the slightly shy yet masculine guys (guys like Archer Hale). They are so rare in romance they are a breath of fresh air. 
 Both characters are full of depth, have interesting backstories but nothing that overwhelms their present. 
 Noah had a bad childhood, ran away (or escape) actually, but Bowen didn't make him bitter towards people in general. Instead he is honorable, a little reclusive, but he has friends and he loves kids. I also love how the author didn't need to tie up all his loose threads and make him forgive everyone from his past within the story. 
 Elise is witty, independent and she is not shy about speaking her mind. She's as honorable and full of loyalty as Noah so it's easy to see why these two souls match. 
 Why not the full 5 stars? Well you have to suspense disbelief a little in an incredible tale. This agency that takes on these cases and uses our heroine repeatedly in different disguises and roles seems the hardest part to accept. But I think readers know what this story isn't going in having read the synopsis. I don't mind it too much as long as the characters and their actions are believable. 
 Another minor flaw, when Noah (view spoiler)[overcame her objections in the end, he didn't present any new arguments, so the delay to their HEA felt unnecessary. (hide spoiler)] 
 Safety warnings (view spoiler)[None. 100% safe. (hide spoiler)]
