[Teresa, The One Who LOVES to Cook]

What Books you have gotten from the Library that you might buy sometime in the Future? Tell me here.

[Lura, The One Who Loves to Write]

Legend series
Shatter Me series (other than book 1, which I do own)
Crusade & the rest of the series (once it releases).
The Dark series books I don't already own. (I have 1-8 or 9, 16, 17, and just bought 22 or 23.)

Loads of others whose titles escape me at the moment. ^_^
