If James Marshall’s George and Martha were not hippos and were both girls, they would be much like best friends Bink and Gollie in this charming early-reader series debut. Tall, quirkily formal Gollie says “Greetings”; the shorter, more casual Bink just says hello. Gollie uses words like “compromise” and “implore”; Bink needs to learn them fast to keep up. Three winsome short stories—“Don’t You Need a New Pair of Socks?,” “P.S. I’ll Be Back Soon” and “Give a Fish a Home”—illustrate the eminently surmountable challenges to Bink and Gollie’s friendship in rapid-fire dialogue that manages to be both witty and earnest. Fucile’s terrific, cartoonish artwork is expressive and hilarious—black-and-white scratchy lines and washes that effectively use spot color to highlight, say, alarmingly hideous rainbow socks or the faint underwater orange of a freshly liberated pet goldfish. One favorite wordless spread shows Bink holding up her goldfish bowl at the movie theater so her fish-friend can see Mysteries of the Deep Blue Sea… seated next to a mortified Gollie. More, please!
