First: I love Bones. 
 Second: I know the show has little to the books. 
 That being said, I mostly liked the character Tempe. She's sure of herself in the field and is easily believable as being the top in her field. Unfortunately, she's a bit over emotional at strange moments, a total doormat in others, and a bit dim at the worst of times. 
 I can see Brennan in there, but at this point in her life Book!Tempe is kind of a big hot mess. 
 I see Booth in Ryan, especially near the end and it's nice the douchebag cop became a bit less douchey near the end as well. 
 As a stand alone book, it made me want to read the second novel. Sure it was a bit overly dry in spots and Brennan was kind of dingy, but you can tell the writer isn't very experienced and the story was interesting enough to keep reading.
