Animorphs
The Scholastic sci-fi series that hooked '90s kids on something surprisingly dark: five teens who can 'morph' into any animal to fight a secret alien invasion. The covers where a kid transformed mid-photo were the whole hook.
Animorphs was the Scholastic sci-fi series that got '90s kids reading something surprisingly bleak. Written under the name K.A. Applegate (in fact Katherine Applegate and her husband Michael Grant), it followed five teens — Jake, Marco, Cassie, Rachel, and Tobias — plus an alien named Ax, who gain the power to 'morph' into any animal they touch in order to fight a secret invasion by the parasitic, brain-controlling Yeerks.
The covers were the hook: an early use of morphing software showed a kid transforming mid-photo into a lizard, a tiger, or a hawk — 55 of them, each about a two-week production. Inside were flipbook morph animations in the corners, a strict two-hour morphing time limit that drove the plots, and a war that got genuinely grim for a middle-grade series.
The main series ran 54 books from 1996 to 2001, spawning a short-lived 1998–2000 TV show on Nickelodeon. Many of the later books were ghostwritten from Applegate's detailed outlines as demand outpaced a single author, but the series' willingness to be strange and serious is exactly why it stuck with the kids who read it.

"If you open the door, turn to page…" These were the skinny paperbacks where YOU were the hero, every few pages forked, and a startling number of forks ended with you dead. The series dates to 1979 and was an 80s sensation first — but the books were still on every classroom and library shelf through the 90s, read with one finger holding the last safe page.
