#3 Calculated Risks by Seanan McGuire

 This is a direct sequel to Imaginary Numbers and is not the best book to jump into the series with.  Due to Sarah having to erase herself from everyone one with her to use that part of their brain to make the math work on the jump to the other universe there is quite a bit of backstory given about how the characters backstory.  Now she has to figure out how to get herself, her cousins that don’t remember her, and several other cuckoos including children that had nothing to do with her kidnapping and get them back without a working copy of the math that got them there and not melt everyone’s brain doing it. They find a few surprises along the way about the dimension they are currently in along with having to fight off the zombie cuckoos that got Sarah in this mess before they were brainwiped during the travel.

There is a novella after the end of this that has Sarah, Artie, and Antimony that is set way before this book that shows just how close the three of them were and how much Sarah lost when she had to remove herself from their memories.  What I like about the novella is that is set at a Comic Con and after a year of no conventions I was really nostalgic for them.
