A Novel

preorder now from St. Martin’s Press.
High in the Rocky Mountains on a secluded campus, sits Hildegard College, a celebrated institution known for its scientific innovation and its sprawling, botanical gardens. Historian Robin Quain has been awarded a residency to examine Hildegard’s impressive collection of ancient manuscripts, but she has a secret. She’s actually on the hunt for an artifact—one she must find before her former best friend turned professional rival gets his hands on it first.
But Hildegard has secrets of its own. Strange sounds echo across the alpine lake, lights flicker through the pines, and the faculty seem more like Jazz-age glitterati than academics. And then there’s the professor who holds the key to Robin’s research. She vanished suddenly last spring. What exactly did she do at the college, and why does no one want to talk about her?
As Robin searches for answers, an unknown source sends her a series of cryptic messages that makes her question whether she’s the one doing the hunting, or whether someone is hunting her. Drawing on historical, botanical, and occult research, and steeped in the gothic tradition, Atlas of Unknowable Things considers what it means to search for meaning in the scientific, only to come face to face with the sublime.

The Little Woods
From Schwartz and Wade / Penguin Random House
People say the woods behind St. Bede’s Academy are haunted, even cursed. So far, three girls have gone missing from the school without a trace. But can a person really just disappear?
When Cally Wood starts at St. Bede’s academy halfway through the year, she’s suddenly thrust into a world of privilege and prestige and in no time flat, she learns to navigate the complex social world of the upper echelon. But amid the illicit romances and weekend-long parties, Cally discovers that brilliant but troubled girl named Iris recently disappeared from St. Bede’s. And Iris wasn’t the first girl to disappear from St. Bede’s. Ten years ago, Cally’s sister was visiting a friend at the school when both girls vanished from their beds.
As Cally tries to unravel the mystery surrounding Iris—one she can’t help linking to her own sister’s disappearance—she discovers that beneath the surface of the elite school and its perfect students lies a web of secrets where rumors are indistinguishable from truth and it seems everyone has something to hide.
