The beautiful gardens are in full bloom at Castleton Manor in Lighthouse Bay, Massachusetts. The upscale literary retreat provides the perfect backdrop for the Hidden Treasures Literary and Gardening Retreat as authors, gardening enthusiasts, and horticulturists descend on the manor. Everything's coming up roses for librarian Faith Newberry as she welcomes her parents to the retreat and prepares for her upcoming wedding with Wolfe Jaxon, co-owner of the manor. But her festive mood withers when the retreat takes a disturbing turn and a guest dies. The death is ruled a murder, and Faith and her friends in the Candle House Book Club set out to dig up clues. But their investigation proves to be thorny. The victim had enemies in spades, and the list of suspects continues to grow. Meanwhile, Faith's clever cat, Watson, hits pay dirt when he makes an incredible discovery. How far will someone go to bury the truth? Faith and her friends must root out the sinister plot before someone else is pushing up daisies.
