The keeper lives in the Winter Woods however, so Tink stows away on one of the baskets being sent over to the Woods. When she arrives, she loses the Wingology book, and the said book is found by a frost sparrow man named Sled. Lord Milori, the ruler of the Winter Woods, tells Sled to send the book over to the keeper. Tink follows and meets the keeper and a frost talent fairy namedPeriwinkle. When Tink and Periwinkle meet, their wings begin to glow, just like when Tink first crosses the border. The keeper, whose real name turns out to be Dewey, discovers that Tink and Peri were born from the first laugh of the same baby, thus making them fraternal twin sisters. The two fairies are more than happy to begin their newfound and strong sisterly bonding, but Lord Milori arrives and informs Dewey to send them back as it is too cold for a warm fairy's wings to withstand.
