I thought this Beauty and the Beast retelling was incredibly well-plotted and an enjoyable read. While it is very (very!) spicy and steamy, author S.L. Prater took the time to show her characters connecting intellectually and emotionally instead of just relying on the fated mates trope. Of Roses and Rituals also has some fun horror elements and surprising depths.
Both Fiona and her love interest, Elias, are dealing with grief. Elias has had time to acknowledge and cope with his, while Fiona has tamped hers down. The treatment of grief here is honest and thoughtful.
