Not every kid skips a rock across a pond and winds up with a unicorn best friend, right? School's out! That means no more teachers, no more books, and lots of time to compliment Marigold Heavenly Nostrils on her good looks. In this third volume, Phoebe and her obligational best friend, Marigold, learn that summer still has plenty of surprises for the both of them. All of our old friends are back - Dakota, upon whom Marigold has bestowed sentient hair; Phoebe's goofy parents, and even Lord Splendid Humility! Have fun as Phoebe and Marigold continue the Phoebegold Detective Agency, spend a week at Wolfgang Music Camp, and find themselves in more misadventures, thanks to Marigold's enchanted sparkles! Along the way, Phoebe makes some new friends, such as Sue - her unique clarinet-playing bunkmate, Florence Unfortunate Nostrils, Marigold's estranged sister, and Camp Wolfgang's lake monster who enjoys tacos and Wi-Fi.
