Dianna Hardy is an international bestselling author of (cross-genre) fantasy fiction, most notable for her dark (often explicit) paranormal fantasy and the raw, intense Eye of the Storm series. But her heart-warming Once Times Thrice series proves she thrives in the light as much as the dark.

Whatever your poison, what she loves most is to bring you stories that are action-packed, fast-paced and not short of heat, with the focus on character development, relationship dynamics, and the plot.

She writes full-length novels and short fiction.

First published in 1997 with poetry, and then in 1999 with her first short story; The Witching Pen was released in 2011 and she hasn't looked back.

Dianna lives in Hampshire, UK, with her partner and their daughter, where she writes full time.

From 2025, Dianna revived her old pen name, and is also writing as Elysa Summers.
