The Infinity Doors
(Las puertas del infinito)

An aperimant is someone with the power to open a door between worlds, between different times and realities. Young Riddly is one of these creatures, and he finds himself in a ravaged London with the Ikari warrior race threatening to destroy the city from the backs of their dragons. Meanwhile, in the world of Collapse, Rebeca has gone from being sold as a slave to working as a disciple for The Locksmith, who sends her on all sorts of missions to gather pieces for a secret key. Both Riddly and Rebeca are unaware that their destinies are linked, and that they will be vital in the fight against many perils.
