The last semester of classes for Sophie Briggs at The School of Roots and Vines is racing to the end. A confrontation and battle with the Serpent, Azdaja, is fast approaching. The legendary Thicket Hall is dying and no matter what the Defenders do, they can only slow the ancient tree's death, not stop it. Could its end lead to a new beginning? If the Defenders can defeat the Serpent. Then death can lead to new life. Graduation, a wedding, a death, a rebirth, and an even bigger surprise await Sophie, Marcus, and the Defenders. Will they be able to put an end to Azdaja for good and use their powers to replant Thicket Hall in time for the next students? Will the School of Roots and Vines survive?
