Icebreaker by Lian Tanner
The plot of this is pretty unusual. 300 years after a mechanical boy is set afloat on an icebreaker in the antarctic, the Inner Circle of the antimachinists have found them and are seeking to destroy the Demon. Petrel, the Nothing girl, is the one to save the ship. Great plot and the characters who develop realistically. Sadly it will be another year until book three is out. sigh. 5th+ Good

Ready Player One by Ernest Cline
I read this to check if it is middle school appropriate. Yes. There is a short discussion of the historical thoughts on masturbation, but in general the language isn't terriible. The concept of the story is terrific. 2044 and the whole world is in an MMO (massively multiplayer online) called OASIS. It provides schooling, entertainment, and the economy is based on it. Otherwise, in reality the world is a wreck. Great plot. Great characters. Awesome conclusion. YA for language, violence, and sexual references. I was put off by his acrimonious atheism. ouch.

65-story Treehouse by Andy Griffiths and Terry Denton
They've done it again. Another 13 stories has been added to the treehouse and the boys forgot to get a building permit. Oh NO! They decide to go back 6 days to get the permit but their time machine keeps sending them to different times and places. Silliness ensues. I love this stuff. 3rd+

Lemons by Melissa Savage
i wanted to like this a lot. The elements were strong- grief, friendship, dreams and hopes, family, and Bigfoot. But it didnt click for me. Maybe it was the internal dialogue. Not sure. 4th+. Okay.

Outrun the Moon by Stacey Lee
Growing up Chinese American in San Francisco involves knowing where the lines are. And our feisty heroine wants the best education she can get in 1906. Finagling her way into an excellent private girls' school, she glimpses what she might have. But literally disaster strikes in The Earthquake. Good historical fiction. Enough sexual allusions to make it YA.

After Tupac & D Foster by Jacqueline Woodson
This is a short but moving story about the summer of the Tupac shooting. Three girls who become connected as soul sisters--two who have grown up together and D Foster who shows up suddenly one summer and becomes entwined with them. Life is confusing, sad and beautiful. Includes the story of an incarcerated gay brother, a smart basketball playing brother, and the mysterious D. Excellent.
