The truth was, I remembered Joanna only through her photos. My family was Jack, age seven; Grace and Claire, six; and our dog, Rose — all of us adopted by Mom, living in a skinny brick town house.

There were lots of days I had dreamed of escaping our crowded home; now, having achieved a college scholarship that would allow me to do that, I was getting sentimental over sticky hugs, dog hair, even the sharp little Barbie shoes and Matchbox cars left in my bed. I wanted to spend the summer with my family, but I felt I owed it to Uncle Will, and maybe to Aunt Iris, to visit.

Besides, I was curious. With my brain crammed full of chemistry and calculus, world history and lit, maybe it was time to learn something never asked on the SATs: who I was.

THREE DAYS LATER I drove the highway and then country routes with my windows up, AC blasting, and radio blaring, hoping to drown out the roar of a muffler going bad. In my junior year I had bought what I could afford: a ten-year-old Taurus, an old-man kind of car. Once maroon, now faded grape, it was covered with decals from two previous owners, guys with a taste for hard rock. Since the car couldn’t look any worse, I had allowed the twins and Jack to add their own stickers, meaning I traveled with SpongeBob, Batman, Rapunzel Barbie, and Sleeping Beauty. Otherwise, it was a car that any girl would be proud to drive.

Uncle Will had mailed directions to the O’Neill home, which was on the other side of the crek from the town of Wisteria. Missing the driveway on my first pass, I crossed Oyster Creek two more times, then yanked the steering wheel to the right when I saw what looked like “first driveway from the bridge.” I was surprised at how nicely Uncle Will kept the entrance, then I came to the cars lining the landscaped driveway and knew I had to be in the wrong place. I cruised up to a manse.
