In Sonic Boom™: Shattered Crystal, Amy discovers a secret ancient
language and manuscript detailing the history and whereabouts of a Lost
Crystal of Power. The evil and vile villain, Lyric, kidnaps Amy in his
eagerness to get his claws on this long-forgotten power that has been
hidden throughout the jungles and canyons of a mysterious new island.

Sonic must team up with Tails, Knuckles and new friend Sticks to trace
Amy’s footsteps and save her from the clutches of Lyric and his robot
army. By working as a team, they will prove they are stronger together
than they are apart.
