Description
For fans of Starling House and A Discovery of Witches with a Thomas Crown Affair twist: a contemporary New England coven hides the mysteries that lurk in the marshes north of Boston—and how they are connected to the largest unsolved art heist in modern history.
Once, Maeve Ryan was the strongest witch of her generation. But Maeve messed up a spell to contact the Lady of the Fens, an eerie Revenant who lures the unwary to their deaths in the brackish marshlands of the North Shore. Maeve destroyed her reputation, hurt her best friend Ash, and tainted herself with unbound, wild magic that transforms witches into insane Revenants.
With unbound power eating away at Maeve’s mind, all she wants is to get rid of her magic. Forever. But Ash’s research into how the spell went awry leads in an unexpected direction: the Isabella Stewart Gardner Museum, and a link between the Lady and a decades-old art theft worth $500 million. When Ash disappears through a stolen painting’s empty frame, Maeve has to follow.
Inside is the Other Marsh, a haunting, deadly realm where only the Lady’s rules apply. Within this half-world lie secrets about North Shore’s history, Maeve’s failure, and the fate of the masterpieces that disappeared over three decades ago. But as Maeve fights toward the truth, she risks her friendship, her coven, and her life against enemies hiding in plain sight
Opening Line
Birds call from dying limbs, a harvest moon rises, and I take the commuter rail home to rob my grandmother.
My Thoughts
❧ A coven of witches
❧ A competent, obstinate, scrappy MC
❧ A spell that turns paintings into a prison
❧ A horrifying Revenant with a tragic backstory…plotting her escape
❧ The importance of positive relationships!
Let me begin with the latter portion of this book, which was really something else! I would actually call this a horror novel with an urban fantasy setting. The creepy veiled Lady of the marsh following our characters from painting to painting, plenty of violence via physical fights against enemies (both human and not), flocks of birds following the characters wherever they go—all very menacing! Some of the characters begin the story as friends, some as strangers, and some as rivals, but in a satisfying plot arc they are forced to accept one another as allies and fight the evil that plagues the North Shore coven of Massachusetts together. And then there is the joy of seeing characters who have struggled stubbornly finally take hold of their own power, on their own terms. Witches be GOATed!
They want to reduce me to a legend? Let them. I will be the worst fable they have ever written.
But I will say that at the start of this book, there were a few things I noted that seemed like they might be debut novel issues. Stylistically it initially read like a YA book even though its characters and themes are not, every character was first introduced by their race (bonus points for the inclusion of a nonbinary character, though), the pacing seemed a bit uneven, the rules about the magic system and the paintings involved in the spellwork were hard to follow, and a great part of the tension in the narrative relied on lack of communication between characters–a pet peeve of mine, although admittedly having a reason to withhold certain information is much preferable to the miscommunication trope.
Even if the execution wasn’t 100% a homerun for this reader, by the end I was “all in” anyway. Full of magic tied to the land, mystery, coven intrigue, desperation, the uncertainty of shifting of alliances, a tangential romance subplot, and monsters created though tragedy, this was an action-packed tale with a touching and very gratifying narrative arc—a powerful story!
“I mean, on a scale of one to an unbound, undead Puritan witch, how bad could family be?”
