The 8th Circle

Edgar Award winner: Investigating a crooked cop, a private detective gets too close to the case. The investigators of the Conmy-Kirk detective agency don’t work in trench coats, drink on the job, or carry pistols. They are researchers who comb newspapers and government records in search of the tiny details that could make or break their clients’ fortunes. It is painstaking and unromantic, but as co-owner Murray Kirk is about to learn, those details can mean the difference between life and death. The district attorney is cracking down on corruption in the NYPD, and the search is spreading like wildfire, forcing hundreds of policemen to resign in disgrace. When Conmy-Kirk is hired to clear the name of one of the accused, Kirk finds himself falling for his client’s daughter, a moral infraction that draws him deeper into the city’s underworld than he ever wanted to slip. This work isn’t like it is in the movies—if Murray Kirk catches a bullet, he’ll stay dead.

A year ago, Danny Ryan lost his wife and son in a car accident. He's still reeling from the tragedy when Michael Cohen, his friend and fellow journalist, drives into the pond in front of his house with a bullet through his gut. With Michael's death ruled a murder, Danny must work to get his name crossed off the list of suspects, and that means digging into Michael's last article, an expose of the twisted side of Philadelphia politics. But powerful people are ready to kill to protect what Michael was about to uncover, and if Danny's not careful, he'll be next. The dark heart of the city is on display in Sarah Cain's gripping debut thriller, The 8th Circle.

One of the greatest works of world literature, Dante Alighieri’s The Divine Comedy has, despite its enormous popularity and importance, often stymied readers with its multitudinous characters, references, and themes. But until now, students of the Inferno have lacked a suitable resource to guide their reading. Welcome to Danteworlds, the first substantial guide to the Inferno in English. Guy P. Raffa takes readers on a geographic journey through Dante’s underworld circle by circle—from the Dark Wood down to the ninth circle of Hell—in much the same way Dante and Virgil proceed in their infernal descent. Each chapter—or “region”—of the book begins with a summary of the action, followed by detailed entries, significant verses, and useful study questions. The entries, based on a close examination of the poet’s biblical, classical, and medieval sources, help locate the characters and creatures Dante encounters and assist in decoding the poem’s vast array of references to religion, philosophy, history, politics, and other works of literature. Written by an established Dante scholar and tested in the fire of extensive classroom experience, Danteworlds will be heralded by readers at all levels of expertise, from students and general readers to teachers and scholars.

The Paradise, which Dante called the sublime canticle, is perhaps the most ambitious book of The Divine Comedy. In this climactic segment, Dante's pilgrim reaches Paradise and encounters the Divine Will. The poet's mystical interpretation of the religious life is a complex and exquisite conclusion to his magnificent trilogy. Mark Musa's powerful and sensitive translation preserves the intricacy of the work while rendering it in clear, rhythmic English. His extensive notes and introductions to each canto make accessible to all readers the diverse and often abstruse ingredients of Dante's unparalleled vision of the Absolute: elements of Ptolemaic astronomy, medieval astrology and science, theological dogma, and the poet's own personal experiences.
