Wish You Were Here — Elizabeth Langston

She can't forget what she's lost. He shows her there's more to be found.
Months after the loss of her twin, Sara Tucker still struggles to recover. She ought to be getting ready for college; instead, she's frozen in place. But when her plans for the future begin to unravel, Sara realizes she can no longer handle her problems alone.

Grant is a supernatural being, dedicated to serving humans in need. He enjoys his promotion to guardian, but he's restless, too. There's someone he met on a previous assignment that he wants to help--except Sara needs wishes, and Grant's not a genie anymore.

When his league accepts her case, Grant volunteers to go. As he works beside Sara to fix the mess of her life, they may both discover that, sometimes, the best way forward is to find a new path.
