Adam Mansbach’s “viral,” tongue-in-cheek kids’ book for adults, Go the F–k to Sleep is now out. We interviewed Mansbach years ago, pre-frenzy, about other matters. This week also offers up a pair of much anticipated novels for the literary set, The Astral by Kate Christensen (don’t miss Edan’s interview with Christensen today) and The Curfew by Jesse Ball, and a rather specialized tome for fans of literary history, Nom de Plume: A (Secret) History of Pseudonyms.
