Thornhaven Series · Book III
Bridgewater wants a faster answer. Thornhaven knows better.
Thornhaven has learned that magic lasts only when care is shared, named, and freely given.
Bridgewater wants a faster answer.
When a formal packet arrives from the river city's failing Riverworks, Cael Ashford, Miriam Holloway, Sable, and the rest of Thornhaven are drawn into a problem too large for one village to ignore. Bridgewater's leaders want a sealed master charm, one central authority, and a promise that control can keep everyone safe.
Thornhaven knows better.
But proving it means facing public pressure, old mistakes, and a city that has forgotten the difference between responsibility and ownership. To save Bridgewater's water-charms, Thornhaven will have to offer something stronger than control: honest limits, open repair, and trust that cannot be forced.
Thornhaven Series · Book IV
Warm bread. Strong tea. A cat who makes nothing easy.
In Thornhaven, every morning starts the same way: warm bread, strong tea, and a cat who makes nothing easy.
But the black sand on the bakery table will not sit still, and Cael Ashford feels the pull of something his uncle left unfinished. Behind a door that should not open, Eleanor's sleeping doors are beginning to wake.
Some are meant to stay closed. Others are only waiting to be rebuilt properly.
The Driftwood Dragon Sanctuary · Book I
A coastal cozy fantasy about a wounded dragon, a sanctuary worth saving, and a woman who did not mean to stay.
Nora Harris has spent two years going where the work goes, mending other people's animals and never staying long enough to be missed. So when the Port Selby council offers her three months as keeper of a half-ruined dragon sanctuary above the cove, she takes it. The money is real and the leaving is built in.
Then she meets the tide dragon. It will not eat. It watches the sea like it is waiting for something the water already took. The greenhouse is collapsing, the barn is locked, and the town that hired Nora would be glad to watch the sanctuary fail.
Saving Port Selby will not come from a fight. It will come from a wounded town deciding what is worth keeping, and a woman who has spent her whole life leaving, learning what it costs to stay.
About
I write thrillers, sci-fi, and cozy fantasy. Based near Pittsburgh. Started writing because I had stories I couldn't stop thinking about, and at some point that turned into actual books.
The Thornhaven Series is the best thing I've written. The Enchanted Workshop is the kind of book I always wanted to write but took me a while to get to. It's warm, a little mysterious, and full of characters I genuinely enjoy spending time with. If you're new here, start there.
The Enchanted Hearth, Book 2, The Enchanted Charter, Book 3, and The Enchanted Threshold, Book 4, are available now on Amazon. The Tide Dragon's Keeper, the first book in a new coastal cozy fantasy series, is available now too.
