An overdue library book spells big trouble for the thunderbolt-throwing chicken of Asgard in this second epic outing (Thundercluck!, 2018). Dispatched by Odin to fetch the tome back from the fearsome Book Wyrm, Thundercluck and his intrepid teenaged Valkyrie buddy Brunhilde travel to Midgard and other Viking worlds, but fall afowl of Medda, a shapeshifting witch out to steal the book for herself in pursuit of a nefarious scheme to poison the Well of Eternity. It looks like the fat's in the fryer when Thundercluck, bespelled by Medda, turns into a jerk chicken, but the plucky pullet comes through in the clutch. Brunhilde takes center stage in this episode, meeting her warrior/author mom, long exiled from Asgard, at last, but there are mighty feats aplenty for all to show their mettle. Readers will join in the final heartfelt paean: "When facing foes nefarious, and blows unfairly struck, / We have ourselves a feathered friend . . . in mighty Thundercluck!" Frequent scenes of the doughty duo and diverse gods are not seen in their finished form.
