Dog Beach Unleashed (The Seagate Summers #2) [EPUB ebook] 

Remy can’t wait for another summer on Seagate Island. It’s time to bring back her successful dog-sitting business on Dog Beach and see her favorite friends. But instead of sunny days and fun in the sand, the summer is off to a rainy start. Remy and the dogs have cabin fever, and, to make matters worse, her friendship with her longtime pal, Bennett, is starting to feel complicated. What can one twelve-year-old do to create summer magic when the summer doesn’t seem to be showing up?
