The synopsis suggests that there will be three siblings but the sample isn't long enough to introduce us to all three. Katie (KT) is the only one we meet and her father isn't a Donor as the synopsis suggests. He had been in a relationship with her mother. Is the book only told through KT's POV or do we also get the other two siblings POV? I am curious about how the title 806 factors into KT's story and how she meets her siblings. If anything, I would borrow this from the library but it wouldn't be at the top of TBR.
