Ravena Guron is the bestselling author of YA thrillers This Book Kills, Catch Your Death and Mondays Are Murder. Growing up, Ravena always read the last page of books first, but discovering Agatha Christie in her early teens stopped that habit, igniting a love of twisty murder mysteries with jaw-dropping endings the reader never saw coming. A born and bred Londoner, she is a lawyer with a degree in biochemistry, and uses the knowledge she’s gained to plot perfect murders (only for her books, of course). Ravena’s bestselling YA thrillers have been shortlisted for the YA Book Prize, the British Book Awards’ Children’s Fiction Book of the Year and many more. Wren (Lauren) James is the twice Carnegie-nominated author of Green Rising; The Reckless Afterlife of Harriet Stoker; The Quiet at the End of the World; The Loneliest Girl in the Universe; and The Next Together series. They have been shortlisted for the YA Book Prize and the STEAM Children’s Book Award. Wren teaches creative writing for Coventry University, WriteMentor and Writing West Midlands, and has written articles for numerous publications, including The Guardian and the Children’s Writers’ and Artists’ Yearbook. They are the founder of the Climate Fiction Writers League, and are a passionate advocate of STEM further education.
