Croc & Gator 1, Swamp Ranger School 1, Swamp Ranger School /

Despite their differing personalities, Swamp Ranger School classmates Croc and Gator forge a fierce friendship in this new chapter book series by Katzenberger (A Love Letter to My Library). The gregarious, loquacious Gator is flummoxed by Croc's serious, contained demeanor; when the two are paired up for their first class activity, Croc coolly responds, "If that's my only choice, then so be it." But as the two work together--a collaboration fleshed out via cartoon line drawings by Ciccotello (I'm a Volcano!)--Gator learns to temper his responses around Croc, and Croc realizes he can loosen up a little and enjoy himself. After willingly teaming up for--and successfully completing--a scavenger hunt, the duo decides to partner as full-fledged Swamp Rangers. The leads' emotional journey can sometimes be too rigid and saccharine, but the characters' yearning to connect feels organic. In a narrative that highlights burgeoning self-awareness and appreciation for each other's talents, Katzenberger celebrates the fragile beauty of the protagonists' swamp habitat and offers simple messaging about conservation: "It means to protect things from harm and not be wasteful." Ages 6--8. (June)
