El aprendiz de Argéntea (Acero y magia 1)

A dark threat looms over Luxos. The queen has abandoned the country in search of allies, while her subjects wonder how they will survive. Neither the mages in the academies nor the witches in their forests have the solution. The only hope lies in the Beast Mountains, where the legend of a forgotten power awaits someone who dares to claim it. Finn is no hero, not even a knight yet. But when a young witch recruits his best friend to discover if the legend is true, he won't let them go alone. Together, the three will embark on the perilous journey north, where they will discover that not everything is as it seems: not people, not magic, not gods…not even the power they seek to awaken.
