Sixteen-year-old Spinneretta Warren doesn't just have a bizarre name. She's got eight spider legs to back it up, along with fangs, venom, and a pair of siblings as unusual as she is. But apart from the odd stare, nobody in Grantwood, California seems to care that Spinneretta and her family are human-spider hybrids. When Spinneretta's ninth cousin Mark turns up, he claims to have magical powers and is intent on tracing Spinneretta’s family lineage right back to her mysterious spider genes. Spinneretta would prefer to continue her happily mundane life, but Mark is not convinced that Grantwood is as oblivious to the Warrens’ arachnid traits as they appear to be... Then a kidnap attempt almost succeeds in whisking away Spinneretta’s younger sister and her life takes a sharp turn for the extraordinary. With Mark intent on exposing the dark secrets surrounding Grantwood, and an obscure legend that’s just a bit too compelling to ignore, Spinneretta finds herself forced to face a web of lies that has surrounded her family for decades. Could the cult of an eldritch spider god hold the answer to Spinneretta’s origins? Or will the dark legacy of the Warren bloodline prove far more dangerous than she ever imagined?
