Helpful Score: 7
It's a little inappropriate for kids under 13. It's the sequel to ttyl, so you shouldn't read it unless you read the first one.
I love this series! Like the previous book (ttyl) and the book following this one (l8r, g8r), it's written entirely in chat form. Maddie, Zoe & Angela's trials & tribulations remind me of my days in high school. These books give you a good look into high school friendships and relationships.
