El guerrero olvidado (Los Gatos Guerreros. El augurio de las estrellas, 5)

With StarClan divided and causing dangerous discord among the four warrior clans, the spirits of DarkClan are gaining strength. Spinel's role as a spy grows more perilous with each passing day, and Dovewing is plagued by nightmares of her time in the mountains. And then, a stranger appears in the heart of ThunderClan, sowing discord and dividing the clans. As tensions rise and clanmates turn against one another, the warrior cats will be forced to choose who they can truly trust... before it's too late.
