Mr. Impossible, by Maggie Stiefvater

It took me a while to get to this sequel to Call Down the Hawk, because I didn't love Hawk as much as I wanted to, and I didn't want to keep not loving the story about Ronan. Because, Ronan! And Matthew and Declan! I guess there was just too much plot in the first book, maybe? Lots of really weird stuff happening and I wasn't wrapping my head around it.

Mister Impossible sorts out all that plot and makes me care immensely about it. And I guess we needed Hawk to set everything up so that all this amazing character growth could happen in Mister Impossible. Character arcs like you wouldn't believe, people!

Brief backtrack to set context: Ronan Lynch (and his brothers Declan and Matthew) are beloved characters from Stiefvater's Raven Boys series, which I highly recommend, and which you don't exactly have to read before you read this series, but I think you'll care a lot more if you do. 

Mister Impossible is the second book in the Dreamers series, which focuses on Ronan's ability to bring real things out of his dreams—and the consequences of that ability, for both Ronan and his family and for the world. The magic of it is really cool, and I love that Stiefvater makes the consequences so real and Ronan's dilemmas so impossible. Lots of great discussions of identity and personhood and what is reality, anyway? Jordan and Hennessy weren't my favourite new characters in Hawk, but now I love them both intensely.

Excellent twist at the end, I must say! We need a happy ending for all of these characters, dear Maggie: please give us a happy ending for all these deeply flawed, hurt, desperate characters who are so busy blowing themselves up that they can't see how loved they are. Now I have to wait for the third book, arrgh!
