Hasta que me mientas by Adrián Abramo Penilla

When Arcana dreams of becoming a full druid she finds herself still in training, living with her eccentric great-aunt Brezo in a cottage thick with potions and incantations. Meanwhile, Teo has just moved in with his sister, wrestling with the courage to be himself and express his true sexual identity openly.
A late-night error in Arcana’s potion-lab changes everything: Teo accidentally drinks a concoction that binds him to speak nothing but the truth — never lie again. Now Arcana must find the antidote, racing against time; yet as the two spend more hours together, sharing frustration, secrets and unexpected truths, their bond becomes something deeper and far more magical than either expected.
Until You Lie to Me brings together fantasy and romance with a fresh queer perspective: it’s about telling the truth, about the power of being yourself, and about the unexpected connections forged when we drop our masks. Set in a world of druids, magic and potions, the story invites readers aged 15+ to explore themes of identity, acceptance and transformation. With humour, tenderness and enchantment, Adrián Abramo Penilla crafts a narrative that charms both teen-readers and lovers of romance-fantasy alike. Whether you’re drawn to spells and druidic lore or to coming-of-age stories of truth and self-discovery, this novel offers a compelling blend of adventure and heart.
Perfect for fans of young adult fantasy, queer romance and stories where truth becomes the greatest magic of all.
