In Riley’s Really Big Worries, the fourth book in the ECSELent Adventures™ series, Riley's best friend, Milo, sneezes and sprays germs all over him! Riley has many worries, and icky germs are now at the top of his list. But are all germs bad? And do our worries need to take control of our thinking, feeling, and behavior? Learn, grow, and develop alongside Riley and friends as they begin to share their feelings and discover ways to become the boss of their worries.

Riley and his classmates, all beloved characters from Housman Institute's ECSELent Adventures™ program, invite children to join them in understanding that everyone has worries, both big and small, and that by sharing them, they can begin to find solutions to their worry problems. Along the way, they learn what germs are and how each person can help keep germs-and worries!-from spreading.
