I'd rate this at 3 1/2 stars. I saw this book advertised, read some other reviews and decided to give it a try. Here's the bad first and let me get it out of the way. This book has editing and formatting errors, enough so that it provides a distraction when reading. A few of the situations in the book were too contrived or not that funny. 
 However, this is a funny book. There were many moments when I chortled to myself and a few where I laughed out loud. It's bawdy and sexual, but enjoyable to read. Rosie is a virgin at age 23 and decides that it's time to change that. Her roommate, Henry, offers advice and sometimes more as Rosie embarks on a series of dates that go disastrously wrong. Both Henry and Rosie have some growing up to do, but I enjoyed their relationship (though I kept hearing Henry's lines in my head in a British accent, probably because he calls Rosie 'love' a lot). 
 I'd probably read more books by this author, though I'd prefer it if they were edited first.
