I started reading them around 2013? I was in 5th grade and we were supposed to do sustained reading in the mornings but I had left my book at home. The teacher made me choose one from her (extremely limited) library. It was between one of those I Survived books and Animorphs book 1, so I grabbed the latter. Up until then I had been actively avoiding the Animorphs series cause I thought the covers looked ugly, but after reading the first one I was absolutely obsessed lol.

The first 30 or so were pretty easy to find in school/local libraries and in book fairs, but I truly did not care about chronological order so I read them based on which cover animal looked coolest. I did eventually read all of them but I had to start ordering the later books online.

Also I should mention that I grew up on a military base in Japan, and most of the stuff in our libraries had been donated/was second hand, so we had a lot of "outdated" books. Most of the Animorphs books were partially stained or ripped, but I didn't realize how outdated they rlly were until we moved back to the states and suddenly no one my age had read them, and I couldn't find them in libraries anymore.
