Twelve-year-old Simon Thorn's life is almost unrecognisable from just a few months ago. He has a twin brother, an uncle he never knew and his first real friends at the secret Animalgam Academy. Not only is he an Animalgam, he's also the Beast King – heir along with his brother to a bloodline more powerful and dangerous than any other. The only piece missing in this new life is his mother, held captive by his evil grandfather, Orion, who wants to rule the five kingdoms. Simon sets off cross-country with his friends to the reptile kingdom to rescue her. He battles Orion's forces and rogue Animalgams, as well as their own doubts and torn loyalties along the way. Because if they don't stop him from gathering the pieces of a terrible weapon, Orion is going to steal all of the Animalgams' abilities away … starting with Simon and those he loves most first. Packed with even more action and characters to love in a thrilling, immersive world, this sequel is an exciting next chapter in the series.
