The top-selling titles at Petaluma’s Copperfield’s Book Store, for the week of April 30-May 6, 2018.

Sticking tight to the top of the local bestseller list is James Comey’s eye-opening “Higher Loyalty,” now in its third week on the stands. But the most notable entry this week is author-meteorologist Ginger Zee, who’s managed to take the second place spot on both the Adult and Kids/Young Adult lists — with two different books. Her engagingly confessional memoir 2017, “Natural Disasters: I Cover Them. I Am One” tells the story of how she’s juggled a sometimes tumultuous personal life with her impressive career as ABC News’ chief meteorologist. Newly arrived on the Kids/Young Adult list, her debut YA novel “Chasing Helicity: Facing the Storm” — which she read from last Wednesday in an in-store appearance at Copperfield’s — tells the story of a young girl whose fascination with the weather helps her rise above a difficult home-life. The No. 1 spot on the kids list this week, meanwhile, is Aaron Reynolds’ and Dan Santat’s “Dude!” a hilarious picture book about a beaver and a platypus whose outrageous surfing adventure leads to seagull droppings, an unusual use of ice cream, and one very large shark.
