1950s vintage pulp novel cover titled The Jungle Queen and the Serpent Crown.

In the shadowed heart of an ancient jungle temple, Zanara, the fierce and regal Jungle Queen, wields the legendary Serpent Crown—an artifact granting dominion over beast and spirit alike. But her reign is threatened by her twin sister, Mara, a ruthless warrior who seeks the crown’s dark power to bend the jungle to her will. As serpent dragons awaken and ancient stone warriors rise, the sisters clash in a brutal battle of blood and magic. Caught between primal forces and their own fractured bond, only one can claim the throne—and the fate of the jungle hangs in the balance.
