The beloved Princess Posey, First Grader, who has been called "the perfect fictional friend for any first-grade girl", is back in another heartwarming installment to the popular series. Posey is worried about her upcoming spring break: instead of going somewhere for their vacation, her mom says they are going to have a "lazy vacation" at home. What if lazy actually means boring? Fortunately, the next few days are anything but: there are pancakes for dinner, a sleepover with her friends, and a new bike without training wheels! After Posey's first attempt at riding ends with a crash, she's not sure she wants to get back on her bike. But with some encouragement from Grandpa, Posey realizes that being brave means trying again, even if you feel afraid.
