One man's prison is another man's fortress. Alan grew up believing that justice was as simple as throwing criminals in jail. He also grew up believing there was no such thing as a shadow with a mind of its own. A special request to put his photographic talents to use for an interview at the local prison reveals a dark plan brewing there. To stop it and keep his family safe, he may have to form some uneasy alliances. The Prison of Shadows is the second book in Shards of Shadow, an Urban Fantasy series by Joseph R. Lallo, author of the international bestselling Book of Deacon and Free-Wrench series.
