The forest is dying, their kingdom is at war, and Claire's magic is the only hope. Claire understands that the key to defeating Kane lies in mastering her magic. She must venture deep within the Gable Forest, seeking the ancient knowledge of the elusive sprites. But the forest is not what it once was. A dark sickness is spreading, warping both the land and its creatures. She must master her growing magic before it's too late. If she fails, both the forest and the kingdom will fall. Meanwhile, King Talon and his inner circle find unexpected allies in the dwargs, who pledge their strength to reclaim Fort Squall. But the stakes are higher than ever. Talon needs a secret weapon to protect Squall's End and stand any chance of reconquering the fort. As things intensify, Claire and Talon's paths converge. She's not the same girl anymore-she's more powerful, more dangerous, and determined to end the war. But can they turn to each other in the face of overwhelming odds? Or will their choices tear them apart? Koldis the Green is the fourth installment of The Dragonwall Series, where the war is far from over and the battle for the kingdom's future begins now.
