Reward Challenge - stage 2

I don't know if you are anything like me but it is impossible to stop from buying books.  I love it, but sadly my bookshelves and my bank account don't.  When I found The Reading Reward Challenge hosted by Good Golly Miss Holly I knew this challenge was for me.  

The goal of this challenge is not a book buying ban but instead a reward program.  There are different stages and hopefully by the end your TBR pile will go down, but you'll still end up rewarding yourself by getting some new books (plus there are also prizes you can win!). 

Here is how it works

Stage 1      Read ONE Book (you own)       =   Buy ONE Book
Stage 2      Read TWO Books (you own)     =   Buy ONE Book
Stage 3      Read THREE Books (you own)  =   Buy ONE Book
Stage 4      Read FOUR Books (you own)    =  Buy ONE Book
Stage 5      Read FIVE Books (you own)     =   Buy ONE Book

Stage 2: I read The Earth, My Butt and Other Big Round Things by Carolyn Mackler (review) and Where Demons Fear to Tread by Stephanie Chong (review) and I bought Return to Paradise by Simone Elkeles.   

Have you read any of these books?  What did you think?
