This first book is ttyl by Lauren Myracle, great YA author and often found on top banned books lists! Automatically she is awesome. And this book is the reason she makes it on there, though it is a shame some people are deprived of it. It's written all in IMs, which is really fun, but deals with tough issues and growing up (apparently this is a good reason to ban books). I hope someone finds it who will enjoy it!
This second one is a mystery, Down the Rabbit Hole by Peter Abrahams. I left this one in True North Cafe on Cambridge St. I hope someone who will appreciate it finds it!
Go ahead, world, spread the YA love today! Even if it's just reading a YA book or talking about them.
