Swimming and mini golf and reading and hiking and piling all together at one table to eat or solve jigsaw puzzles . . . phew! When the school year ends for a little boy named Ravi, a boisterous family vacation filled with fun activities, delicious food and lots of bonding time begins.  As Ravi explains in Newbery Honor winner Rajani LaRocca’s sweetly nostalgic Summer Is for Cousins, he and his parents, sister Anita, aunties, uncles, grandparents and five cousins all stay in “a house that’s not any of ours, / near the ocean / and a lake.”  It’s always wonderful to see his family again, but Ravi is feeling a little uncertain this year. His older cousin Dhruv has grown up so much; his voice is deeper, he’s gotten even taller, and what if he doesn’t remember that he and Ravi have the same favorite ice cream flavor? (It’s banana—delicious but hard to find.) Fortunately, as the pages turn and the days pass, Ravi is able to put aside his worries and remember how kind and supportive his cousin is. With Dhruv’s encouragement, he even goes on the rope swing he was too afraid to try last year! “Dhruv is my big cousin,” Ravi thinks, “but now I’m bigger, too.” Abhi Alwar’s colorful and emotive illustrations enhance the warmth of LaRocca’s appealing tale, empathetically conveying Ravi’s initial hesitancy and burgeoning confidence. All 15 family members have charming visual cues, too, so readers can spot their favorites on every page. For example, shutterbug Anita is never without her instant camera, while Puja’s barrette keeps her hair in place whether she’s building sandcastles or barreling along on a bicycle. Animals get in on the fun too: An energetic dog frolics across the pages, and inquisitive ducks avidly supervise the family’s water-based activities. Summer Is for Cousins nicely hits all the emotional beats of a superfun family-filled vacation and reassures readers that people may grow and change, but affection endures.
