Bøger i Zaria Fierce serien

An Old Challenge, a New Mission Successfully securing their new feathery companion should've meant the end to their secret mission was near, but Christoffer Johansen learns it's only just the start. With superstitious river-trolls and bickering white ravens on the one hand, and a shockingly gleeful brownie and witch on the other, he can hardly make hide nor hair of what's to come. Something, though, is coming and it glides sinisterly just beneath the surface.
