The B**** Queen's Prize

Publisher's blurb: At first, it seems like a straightforward commission for a party of heroes: A Waterdeep merchant hires you to recover a valuable item for her from a shipwreck in an area where dangerous monsters are known to prowl. But there is more to that item than you knew when you set out, and you find yourself in conflict with an enthusiastic sect of Umberlee devotees who want it at least much.
