Skylar Snow, 13, was the youngest of three siblings, a budding graphic designer who spent most of her free time sketching on her tablet.

Mom‑and‑dad‑time at the Snow house was a rare commodity, and Skylar often found herself taking on the role of “mini‑parent” for her brothers, especially when Mara was out on location.
