no it's not quite the same, in the books tempe works for 2 different labs and not at the smithsonian and Ryan in the books is not in the show, it is a character played by David Boreanez, I've watched the show from season 1 and it's at season 9 now, she does not have a daughter in the show nor has she been married.
I think i have up to season 5 on dvd.
In the tv show, tempe is a writer of novels though with the pen name kathy reichs lol
when they were looking for a new intern they tried different characters and that was very good, i'll not spoilt it for you though, you can probably pick up the first few series for about £10 on ebay, or you can probably watch them online
I've read all of Kathy Reichs books and also seen all episodes of Bones, they're quite different but each offer something you might like. I find the books to be darker than the show, which to me has a light hearted side, the lead character Tempe Brennan is socially inept and has a very good story about her past.
We watch this show religiously. It must be popular, it's even on TV here in NZ! If I have a criticism, it's that I don't really like Emily Deschanel's acting, and it would appear the norm in Washington DC is to strip all cadaver's of their skin and determine the murderer from the skeleton alone.
Entertaining none the less.
