Rosemary Mosco is a science writer and artist, and she's passionate about sharing her love for the natural world. She writes and draws the science webcomic Bird and Moon (birdandmoon.com) and makes the urban nature webcomic Your Wild City (yourwildcity.com) in collaboration with fellow First Second author Maris Wicks. She has served in communications roles for nonprofits such as Mass Audubon and NPS, written for nature publications, and led unique nature walks. She holds an MS from UVM's Field Naturalist and Ecological Planning Program. If she could explore any place in the solar system, she would travel to Jupiter's moon Europa. Then she'd come back home and visit her favorite nature preserves on Earth, where she'd observe all the strange creatures and think about the possibilities for life on other planets.
