Dive deep. Get Salty.

Mermaids and Merliens
Book One

Calling 1.png

A Jersey Shore lifeguard. An immortal mermaid.

An apocalypse churning beneath the waves.

Jonah Whitmore wants little more than a quiet summer in the sun, until the old man he'd just saved whispers a single word.

Merliens.

Something inside Jonah shifts, and hours later, his legs twist into an emerald-green tail, binding him to the sea.

Desperate for answers, he follows the reckless and curious mermaid, Mezzy, into Atlantis, where an entire civilization has been cut off from their home realm of Mercadia.

And Mercadia is dying.

The only way back is a portal that responds to one thing: Jonah and Mezzy, together. The deeper Jonah goes, the harder it is to leave.

Book Two

The apocalypse slows for no mermaid.

Jonah walked out of the ocean and back into his life. Except someone else was already living it.

With a doppelgänger occupying his place on land and Mercadia collapsing behind him, Jonah can't go back and he can't move forward. The Void is swallowing everything, and the queen mother is making a desperate move to escort all mermaids to Earth.

But Earth isn't ready for the unyielding parade of mermaids. And neither is Jonah.

Together, he and Mezzy have one last shot to stop the tide.

Book Three

Where Mercadia ends, Camelot begins.

Jonah and Mezzy thought saving Mercadia would be the hard part.

They were wrong.

Swept through time and dropped into the court of King Arthur, they find themselves caught between a crumbling legend and a rising threat. Viviane, the Lady of the Lake, has stolen Merlin's powers and she has no intention of giving them back. Without Merlin, there's no way home. Without a way home, Mercadia is finished.

Knightly jousts, wicked magic, and an ancient sorcerer with his own agenda stand between Jonah and Mezzy and everything they've fought for.

Some legends are better left unbroken.

Mermaids and Merliens
Book Four

The realm-shattering conclusion to the Mermaids and Merliens series.

Mercadia is void. Earth is next. Long live Mercadia.

 

The mermaids have arrived. All of them.

With nowhere left to go, an entire civilization has surfaced on the Jersey Shore, and Earth is not prepared.

 

Humans are transforming into sea creatures. The government is rounding up anyone with a tail. 

Somewhere in the midst of all this chaos, Jonah and Mezzy are running short on time and falling out of options. After everything they’ve been through, they know what they want. They just have to survive long enough to get it.

Two species. One ocean. Infinite possibilities.

Dive deep one last time.
