Interlocking Pieces, by Molly Glass

Now we get back to fiction that looks like fiction.  Our protagonist wants to meet her brain (well, part of brain) donor.  I think this is a universal need--to meet biological parents, to wonder about the person that made your life possible.  So we see a very natural impulse played out here, in a sensitive way.  Not a big stretch, but Interlocking Pieces (found a legitimate-looking free source, staying true to the blog) is a nice little read.  Still 2 stars.
