The second one I read is called Book Scavenger" by Jennifer Chambliss Bertman. It's about a girl who loves puzzles and has moved a lot of times (her family has set a goal of living in all 50 states and is writing a blog about it). Emily also loves playing a game called Book Scavengers (which I was crushed to find was actually fictitious! Rats! I really wanted to play it!), which is an online game where you hid books and post clues on line. People can earn points by finding the book first. Her new town, San Francisco, starts off different right from the very start. First, she makes a new friend almost immediately. James lives in her building and is also a big puzzle fan, which is good because her brother has developed his own interest in music and is kind of leaving Emily behind. Second, San Francisco is the home of the Book Scavenger founder, so Emily is really excited to be so close! There is also an attempted murder, skulking bad guys, excellent ciphers, and a ton of literary references. If you liked "Escape from Mr. Lemoncello's Library" by Chris Grabenstein, you are going to love this one.
The last one I read is called "Max the Brave" by Ed Vere. This one is a picture book and I'm not sure I'm really going to be able to give this one what it deserves. I downloaded it from Netgalley and I hope this isn't the way it's supposed to be, because the way it was, was a pain. First of all, the orientation was a bit wonky. When I had my iPad in landscape, the book formatted to portrait. When I turned the iPad, the book turned too. So I basically had to read it sideways. But ok, it's free. The second thing though was that it felt like the pages were out of order. On one of my pages, Max the cat is saying yuck and looking behind him as he runs away. But it there isn't anything on the page before it to give you any indication of what might be yucky. Anyway, it's a cute little story with simple pictures and apparently Max is trying to catch a mouse but he doesn't know what a mouse looks like, so he keeps asking. It's a bit like P. D. Eastman's "Are you my mother?". I will look for it in a real book rather than trying to read it online.
