Catch some sun and ride the wave as the aquatic adventure continues in 'Waves of Change' Part Three! Sonic faces a city invasion by the ominous Dark Gaia Monsters! To make it even worse, the invasion is underwater-and Sonic can't swim! As the struggle turns desperate, will it be Amy's mission to find the key to saving them all, or will Sonic be left to drown? Then, in 'The Light in the Dark' Part Two, the Freedom Fighters find what they're looking for-but will their own divisions bring them down? Featuring new cover art from Ben Bates and an extra-special 'monster movie' variant from artist T.REX!
