Lioness Rampant is the final installment in Tamora Pierce's celebrated Song of the Lioness quartet, which has been honored with the Margaret A. Edwards Award. Alanna of Trebond has achieved her dream of becoming the first female knight errant, but she finds herself at a crossroads, uncertain of what her next step should be. Despite her legendary triumphs in countless battles, Alanna realizes that there might be more she needs beyond the life of a knight errant.

However, Alanna's reflections are put on hold when she faces an impossible challenge. She must secure the Dominion Jewel, a gem of legendary power that can bring great good when wielded by the right hands. But time is of the essence, as the kingdom of Tortall faces grave threats from all sides. Enemies, both powerful and petty, are conspiring to destroy everything and everyone that Alanna holds dear.

As Alanna embarks on this perilous quest, she discovers that her future is indeed as epic as her past, both as a formidable warrior and as a woman forging her own path.
