A hidden mermaid society. A forbidden human romance. A deadly curse rising from the sea.

Lia Nautilus is a mermaid, but she’s never lived in the ocean.

Instead, she navigates high school in Malibu while hiding a dangerous secret: she belongs to a hidden community of land-dwelling Mer forced ashore after a devastating curse stripped their people of immortality.

Since the infamous Little Mermaid unleashed war across the seven seas, the ocean has never been safe. So, Lia has strict rules. Don’t reveal the truth, don’t trust humans, and definitely don’t fall for one.

But staying away from Clay Ericson is harder than surviving P.E. class. Getting close to a human could expose her entire mermaid society. And Clay is already falling for the mysterious new girl at school.

A girl who isn’t what she seems.

When Lia discovers she isn’t the only one hiding a supernatural secret, she realizes Clay is in far more danger than he knows. To protect him, she’ll have to break every rule she’s ever followed even if it means risking her family, her people, and her heart.

Emerge is the first book in The Mer Chronicles, a sweeping YA mermaid fantasy series filled with forbidden love, ocean curses, and underwater secrets.

Lia Nautilus helped shatter the Little Mermaid’s curse and restore hope to Merkind, but breaking ancient magic has consequences.

Lia is determined to spend her senior year on land with Clay, the human boy she risked everything for. But while Malibu feels safe, the sea is shifting. A new underwater capital rises from the ruins of war, and Lia’s family is summoned below the waves to stand trial alongside the powerful and dangerous Melusine.

Secrets long buried will surface. Secrets about Lia’s power, her heritage, and the fragile peace holding the ocean together. As political tensions mount and old rivalries ignite, Lia finds herself torn between two worlds.

When questions about Clay’s future collide with her growing connection to the enigmatic Caspian, Lia is forced to confront feelings she can no longer ignore. Trust becomes a dangerous gamble.

To uncover the truth, Lia leaves her sheltered Malibu home for a remote and mysterious academy for mermaids. A hidden school where ancient magic is studied and guarded.

Because breaking a curse was only the beginning.

Immerse is the spellbinding and breathless final installment of the Mer Chronicles series where descendants of the Little Mermaid must face deadly magic, shifting alliances, and the dangers of forbidden love.

A royal coronation. A resurrected enemy. An ancient ritual that could destroy the sea.

Lia Nautilus is finally living beneath the waves in the glittering palace of the new underwater capital. With her parents’ coronation approaching, peace seems within reach for Merkind.

But peace has never lasted long in the ocean.

While Lia secretly slips away to Malibu to be with Clay, the human boy she refuses to give up, shadows stir Below. When a powerful enemy resurfaces and palace security tightens, Lia is confined to the sea. Torn once more from the life and love she fights to protect.

As political tensions rise in the underwater kingdom, Caspian drifts toward dangerous alliances, convinced even the cunning Melusine is capable of redemption. When Melusine appears at the royal coronation ball on Caspian’s arm, old wounds reopen, and Lia realizes their fates may be far more entwined than she ever imagined.

Because darker magic is awakening.

An ancient ritual long buried beneath the sea threatens to reshape Mer society forever. Lia must decide whom she can trust: the human who holds her heart, the best friend losing his way, or the enemy who may be the only one powerful enough to stop what’s coming.

Saving the ocean may require the one alliance Lia never thought possible.

But trusting Melusine could cost her everything.

The thrilling final installment of The Mer Chronicles delivers high-stakes romance, sea-bound destiny, and a heroine forced to choose between love and the future of her world.
