Books that you may have not read yet... and are definitely worth reading in my mind:

All books belong to their respective owners:
 Alice I Think series by Susan Juby
 A Wrinkle in Time quartet by Madeliene L'Engle
 Pride and Prejudice by Jane Austen
 Persuasion by Jane Austen
 The Road by Cormac McCarthy
 Anne of Green Gables by Lucy Maud Montgomery
 ttyl series by Lauren Myracle
 A Ring of Endless Light by Madeliene L'Engle
 A Corner of the Universe by Ann M. Martin
 Belle Teal by Ann M. Martin
 Poems of Emily Dickinson
 These two are ones that pretty much everyone I've met have an opinion on but I thought I should include them because I'm such a big fan of them both..
 Harry Potter series, especially The Prisoner of Azkaban, The Order of the Phoenix or The Deathly Hallows
 Twilight Saga by Stephenie Meyer (that's right I like BOTH Harry Potter and Twilight...)
