Love must be stronger than fear, stronger than fate.
Invincible.
The future of two worlds depends on it.
Joy Malone has learned to live between two realities, surviving mortal threats and agonizing betrayals. And she's found true love. But the world of the Twixt is in chaos, and the Council wants someone to blame.... Facing a danger greater than any she's ever known, Joy must find the strength to rely on herself as her allies fall away, because Joy is no longer sure just who - or what - she is. She knows only that her deepest secret is also her greatest vulnerability and the key to saving them all.
As she fights to protect her friends and family and to unite two disparate worlds, Joy has to trust that some bonds are stronger than magic.
True evil is rarely obvious. It is quiet, patient.
Insidious.
Awaiting the perfect moment to strike.
Joy Malone finally knows who she is, where she comes from and how to live in two worlds at once. And now she can introduce her family and friends to her mysterious boyfriend, Indelible Ink. But when Ink's twin sister, Invisible Inq, calls in a favor, Joy must accept a dangerous mission to find a forgotten door between worlds—a door hiding a secret that some will kill to keep.
Unseen enemies, treasonous magic and an unthinkable betrayal threaten both the Twixt and human worlds as Joy races to expose an ancient conspiracy and unleash the unalterable truth—some secrets cannot remain secret forever.
