The style of this book reminds me a lot of Sunshine by Robin McKinley. We get a lot of internal dialogue from the main character - and it is similar to Sunshine in that it's almost like actual thoughts. Instead of following a straight narrative path we are reading the main character's thoughts as they appear. It can be a little jarring at first to get into, but I really do appreciate this style choice.
Be forewarned, this is go Charlotte Stein so it's some steamy stuff not for the faint of heart.
