The Unwritten Heir by Cosette Verga:

4 stars

A year after a traumatic event, seeking closure, Riven accidentally creates a portal to a world that’s not supposed to exist. Drawn by something she can’t explain—and reckless with grief—she steps through and finds herself a pawn in a contest she never wanted to enter. Yet the longer she plays, the more she wants to win.

The Unwritten Heir starts boldly, with the kind of tragedy that comes from mixing magical teens and alcohol, dusted with foreshadowing. The narrative then jumps forward a year, and Riven is still embracing the party life—only now with an edge of impetuousness that is at once understandable and off-putting. The tension deepens when one parent knows about her behavior—and the other doesn’t.

As the story unfolds and the stakes sharpen, significant character development follows. Riven is forced to confront very adult realities, facing the dark unknown and the cruelties that sometimes haunt life. She grows up.

The cast of characters is an interesting mix. Toran is well-drawn; I appreciated that he doesn’t waste time feeling sorry for himself. Ophelia and Chloe are convincingly mean, if somewhat archetypal. Selena, Elara, and Trish occasionally blend together and could benefit from more distinguishing moments, as could Calvin and Tony. Caelan is loyal and has an intriguing ability, but he, too, could use a bit more development.

The dialogue, plot, and pacing are strong enough to support the arc, though not exceptional. I don’t want to sound overly harsh—I did enjoy the story. It has all the necessary working parts, but at times can feel structurally familiar, with the exception of the cliffhanger ending.

The emotional impact, however, worked, full stop. The early trauma, Seyla’s situation, Toran’s backstory—there’s no room for indifference. I was invested.

The Unwritten Heir is an enjoyable addition to the romantasy/fae court landscape, well-suited for readers who enjoy court trauma, questionable choices leading to love, fated bonds, and abrupt endings. Fair warning.
