Applegate Katherine Alice. Megamorphs 03. Elfangor's Secret

The former Visser Four inadvertently discovers the Time Matrix and uses it to rewrite history to make the Yeerk domination of Earth much easier - America is now a technologically inept, genocidal empire; Jake is a neo-Nazi who demands to be called "Supreme Leader" by the other Animorphs, and Rachel is in a re-education camp to be "taught her place", her role on the team now being filled by Melissa Chapman. None of the Animorphs are aware of the change, as this is, to their minds, what life has always been like, Visser Four having changed events before their births. The Ellimist and Crayak have formed a temporary truce in order to stop Visser Four, and they send the Drode to offer the Animorphs, having restored their true memories and line-up, a Hobson's choice; they can refuse the opportunity to track down Visser Four, and the timeline remains as it is, or they can defeat Visser Four and return the timeline to how it originally was. for the price of one of their lives. The Animorphs of course have no choice but to accept, and set out to stop Visser Four's rewrite of time.Megamorphs #3: Elfangor's Secret is the third book in the Megamorphs series, a spinoff of the Animorphs series.
