A Dream So Dark by L.L. McKinney

Still reeling from her recent battle (and grounded until she graduates high school), Alice must cross the Veil to rescue her friends and stop the Black Knight once and for all. But the further she ventures into Wonderland, the more topsy-turvy everything becomes. It’s not until she’s at her wit's end that she realizes—Wonderland is trying to save her.

There’s a new player on the board; someone capable of using Nightmare creatures to not only influence the living but raise the dead.

Dreams have never been so dark in Wonderland, and if there is any hope, Alice must confront the worst in herself—and in the people she loves—and face the very nature of fear.
