In this all-new anthology, Neil Gaiman pierces the veil of reality to reveal the enigmatic, shadowy world that lies beneath. Please Secure Your Mask Before Helping Others includes previously published pieces of short fiction—stories, verse, and a very special Dr. Who story that was written for the fiftieth anniversary of the beloved series in 2013—as well as a tale written exclusively for this volume. A writer whose creative genius is unparalleled, Gaiman entrances with his literary alchemy, transporting us deep into the realm of imagination.
