If you loved Millie’s sharp, flawed voice and her journey dealing with mental health challenges while unraveling faerie intrigues, you’ll be drawn into Every Heart a Doorway. Here, Nancy and other misfit teens cope with trauma and identity after returning from magical worlds, blending emotional honesty with a fantastical setting.

If Millie’s dry humor and snappy comebacks made Borderline a delight, you’ll appreciate Myfanwy Thomas’s sharp wit as she wakes up with no memory—right in the middle of a supernatural government conspiracy. The Rook balances intrigue and action with a deft, comedic touch.

If you were fascinated by Millie’s sometimes unwise, always complex decisions and her willingness to bend the rules, Vicious offers a compelling cast of characters whose superpowers are matched only by their moral ambiguity. Victor and Eli’s rivalry is a masterclass in gray ethics and anti-heroic choices.

If the gritty, secret faerie society of Los Angeles in Borderline fascinated you, you’ll love the New York magic underworld of An Unkindness of Magicians. Sydney, a powerful outsider, navigates treacherous magical politics and dark secrets in a city hiding a world of spellcasters.

If you appreciated Millie’s raw, transformative journey as she finds her place and power, The Girl with All the Gifts delivers that same punch. Melanie’s evolution from a sheltered experiment to a force who changes her world is both heartbreaking and deeply satisfying.
