Furthermore

Furthermore, by Tahereh Mafi, is a book about a unique-looking girl named Alice Alexis Queensmeadow. One day, Alice's father goes missing with only a ruler taken along with him. Six years later, she sets of on a journey to find him, no matter the risks that come with it. 

Release Date??? Cover???

Furthermore is set to release on August 30th, 2016. More than half a year away! The cover hasn't been released either, but I'm pretty sure it will come out in a month or so, so hold tight. The date you can pre-order it is also not said either, but I will definitely update this blog post once more information is released! Two things that are confusing me are:

1.) The way it's worded on Goodreads. I can't tell if she is 12 or six years passed and she's 18.

2.) If it's a middle grade (Junior High) book or a YA/Teen book? 

I'll make sure to clear this up soon!
