I don't know.. maybe 3.75? Maybe 4? It was good, don't get me wrong... I just wasn't as interested in this book as I was the first in the series. It seemed a lot of the same... and just kinda predictable. Also there was a LOT of sex and normally that doesn't bug me, but it actually got old.
Good read still.
Edit: ALSO I really love Tim. He is super-duper awesome and authoritative and that's totally hot.
