A teenage girl, Ecila Johnson, leads a normal life—her only connection to Wondaland is through hazy bedtime stories told by her mother. At her older sister's whimsical garden wedding, something strange stirs: a flash of white fur. Ecila spots a peculiar rabbit in a waistcoat darting through the hedges. Pulled by curiosity (and something deeper she can’t explain), she chases him—and tumbles into a hidden hole beneath a willow tree.
