Something Like Home, by Andrea Beatriz Arango

Laura has never really been around her aunt before, but now she is living with her.  And it's all her fault.  It was Laura, after all, who called 911, which led to the police taking her parents away and a social worker taking her to her aunt.  But it's OK, because Laura is going to make things right and she'll be back with her parents by the end of the week!

And when things don't work out quite as she planned, Laura finds that there are other solutions. Like the abandoned stray puppy that she brings home and trains to become a therapy dog.  Like the boy at school whom no one likes, but who Laura learns is dealing with his own problems.  Or like her aunt, who is struggling just as much as Laura to figure out this new arrangement.  

A sweet, albeit rather predictable middle grade book in verse about a girl figuring out how to adapt to changing circumstances she cannot control (and finding a few things that she can control along the way).  It contains a smattering of Spanish and Laura and her family are Puerto Rican, but these are not particularly integral to the story (despite the novel being a Belpre Honor book).  Instead, the story deals with the concept of family and home and how both are wherever you find them.
