Toshie the Hero and The Shapeshifter's Mask. Toshie the Hero, #2

Toshie died on Earth and woke up as the Hero of Vara Elma. She's accepted this isn't a dream. But her nightmares keep getting stranger. Yrlith is missing, and everyone can tell Sally is only pretending to be fine. Navarin failed her mission, and the guilt is getting to her. A sleepless Brot tends to the poisoned Princess Alamode, but she is only getting worse. Trust is becoming costly. Hildetarte escapes with Livervurst and Biscuit, only to find themselves in the hands of the dying Kaerin Empress.
Yrlith wakes up completely separated from the party and meets the last person she ever thought she'd see: her own mother. Toshie the Hero and the Shapeshifter's Mask is the second book in the Toshie the Hero series-an isekai fantasy where Toshie was given the title of Hero, but now she has to earn it.
