I found an archive of all the Animorphs books and, for some reason, thought that reading through them for the first time in well over 20 years was a brilliant idea.

There's interesting bits here with how morphing works and stuff, but I definitely wouldn't recommend this nowadays. It's surprisingly brutal for a children's book (as all the good ones are) but it is still a children's book, and the simple language and plot really holds it back from being a really good read.
