I was just talking to a friend of mine about books we read from our childhood, and I described one in particular that I really liked. But I can't remember the name of it.

The main character is a girl, maybe middle school to early high school aged. She has an artificial leg, but I can't remember the circumstances surrounding it. The book talked about how she was embarrassed about it, and always wore long pants to cover it. Never shorts.

The other thing about her is that she rescued dolphins. At one point, she found one near death, and stayed with it all night keeping it afloat so it wouldn't roll over from weakness and drown. Eventually, the coast guard or some other person eventually found her and intervened, getting the dolphin to a care facility.

She visited the care facility often, and I remember the book describing how she made a cream to put on the dolphin's wounds that was similar in texture to peanut butter.

I also remember the book describing how she would remove her artificial limb before getting into the pool with the dolphin, and at one point, her classmates saw her in the pool with her stump (sorry if that's an offensive term) exposed, and her being absolutely mortified.

I also remember that maybe she lived on a houseboat with her parents?

I thought maybe it was "For Love of Jeremy" by Hazel Krantz, but that's not it.

Thanks!
