Pica - The Gaia Trilogy

Luke hates nature, preferring the excitement of computer games to dull walks in the countryside, but his view of the world around him drastically begins to change when enigmatic loner, Guy, for whom Luke is reluctantly made to feel responsible, shows him some of the secrets that the very planet itself appears to be hiding from modern society. Hidden behind the everyday screen of school family-life, Luke tumbles into a fascinating world of magic and fantasy, where transformations and shifting identities become second nature.
Luke gets caught up in an inescapable path that affects his very existence, as the view of the world around him drastically begins to change.
