Lightning Shell marks the dramatic conclusion to the People of Cahokia sub-series by bestselling authors W. Michael and Kathleen O'Neal Gear.

Spotted Wrist's squadrons are about to launch an assault on Evening Star Town. Meanwhile, the new Keeper's loyal squadrons have taken control of central Cahokia.

Blue Heron's enemies have declared her dead, a supposed victim of the fire that consumed her palace. She's alive and in the end it will be her wits, Seven Skull Shield's licentious cunning, and a desperate gamble that determine who lives and who dies in Cahokia.

Meanwhile, in the distant east, a desperate three-way race is underway. Walking Smoke-the Lightning Shell witch-hastens to make his way back to Cahokia, understanding that the cure for his impotence lies atop Morning Star's Mound.

Night Shadow Star means to stop him before he can get to Morning Star. Following in her wake, Fire Cat is merciless. He will stop at nothing to ensure that it is he, not Night Shadow Star, who pays the ultimate price.

The final showdown will shake Cahokia to its roots, and nothing will be the same again.
