A little known but amazing book by Neal Shusterman, a highly recommended author. Neal Shusterman also wrote the Skinjacker Trilogy (Everlost, Everfound, and Everwild) Unwind, along with several other science fiction/fantasy novels. All are very well written with amazing plots and lovable characters.

Bruiser and Unwind are two of my all-time favorite books. If you haven't read them....You need to.

5.
a baby who is (a) big and fat when he/she is born and/or (b) gave his/her mother a lot of kicks and squirms during the pregnancy.
New Mom's Friend: Wow, look at that baby! He's huge! And he is downing that bottle like he is 10 months old.

New Mom: I know, but he's only 3 weeks old. He just takes after his dad and me since we're both tall. Little Bruiser. He's a hungry thing! And we was too big to fit in my belly for the last 2 months of me carrying him. He was always squirming around and kicking me hard.
