Particular thanks are due to Felicity Pors at the Niels Bohr Archive, who told me the story of Hevesy’s cats that prompted me to get hold of Hevesy’s delightfully titled collection of scientific papers, Adventures in Radioisotope Research, and to the friends who made my northern travels so pleasurable, especially Troy Selvaratnam, Vijai Maheshwari, and Tarvo Varres. Brent Buckner hosted much of the writing, kept me more or less sane in times of adversity, and gave useful comments on several rounds of draft. My father, Ian Davidson, offered scientific fact-checking at various stages. The book benefited immeasurably from editorial comments from Zareen Jaffery and Ruth Katcher. Thanks, too, to Kathleen Anderson, Liz Gately, and others at Anderson Literary Management. So many friends, family members, and students facilitated the writing of the book in one way or another that I really cannot begin to list them here, but I am immensely grateful for their contributions, and for the work of everyone at Harper-Teen. Finally, I would like to thank the bloggers who greeted The Explosionist with such enthusiasm and asked for the sequel. I hope Invisible Things will meet or exceed their expectations.
The original inspiration for this story was Hans Christian Andersen’s “The Snow-Queen,” a tale I have loved ever since I first encountered it as a small child reading Andrew Lang’s The Pink Fairy Book. Go and read it if you have not already!
