“Until I Find You” by Rea Frey is a story filled with darkness and loss. There’s a lot of loss going on from main character Rebecca Gray’s point of view. In fact, one of the losses is her sight. She has a degenerative disease and can only see shadows, and she knows her sight will get worse and worse. To make matters even darker, Rebecca is a widow. Her husband died when she was newly pregnant, her mother shortly after that, and her grief at losing her husband, her mother, her sight, and the life she envisioned is quite overwhelming.

It’s fascinating to learn how Rebecca manages life with a baby. She diapers him, changes and bathes him, feeds him, and takes him for walks in Elmhurst, the suburb of Chicago where she grew up. She lives in the house she grew up in and is able to function there perfectly; she also navigates her way to the nearby park and friends’ houses. Her strength and her determination not to let her blindness hamper her become a stumbling block when she ventures out determined to not rely on anyone else. At times, we want to shake her and tell her that it’s permissible to let others help; that people who are sighted rely on others, and she certainly can, as well.

The story is told from alternating perspectives, that of Rebecca — labeled “Bec” and told in first person narrative — and that of Crystal, one of Bec’s new friends, told in third person narrative. Crystal and Bec met at a grief group and became friends. They live within a few blocks of each other in Elmhurst. Both Bec and Crystal are very unhappy. Both are widows, both have a child, and both are suffering severely. Bec is the center of the story, and her grief is compounded by all her other losses. Her life seems very dark at the start of the story. She imagines that someone has been watching her inside her home. She finds her front door unlocked when she is sure that she had locked it. She finds the baby’s playpen moved from the room she kept it in to another room. As readers, we believe her, but we also wonder if she is a completely reliable narrator. Is her emotional state causing her to imagine things?

The one bright spot is that an old boyfriend, Jake, who she believes is the love of her life, is back from out of state. He texts her and wants to meet. He knows that she is widowed, and when they meet, she realizes that she’s still in love with him. But when her baby disappears and is replaced with another infant, will he believe her? He’s a Chicago detective, so he could be the perfect person to help her find out what happened to Jackson.

Bec knows her baby. She knows what Jackson smells like, feels like. She knows every inch of him because while she can’t see him, she feels him, she touches him. She knows the patch of eczema behind one ear and the notch on his collarbone. The baby in the crib in her house is not the quiet placid Jackson who never cries.

But what do you do when no one believes you — her friends, most of whom have never really held Jackson or spent a lot of time with him, the police who were called to her home when she thought someone had been inside, and maybe even Jake. Bec knows she’s on her own, and she knows unequivocally that the baby isn’t hers — even if no one else believes her.

The story takes off at this point, and while we don’t know quite what to believe, we know that Crystal’s life, too, is far from perfect. Crystal’s narrative is vague, and there are omissions. Her ten-year-old daughter Savi is a talented cello player, and Bec, who was a symphony cellist, gives her lessons. But Savi is unhappy because she knows her mother is unhappy. While she has fun with the nanny, a young woman named Pam, we get the feeling that Pam isn’t what she appears to be, and that she’s hiding something.

The mystery of where Jackson is, how Bec will figure it out, and who her friends really are intensifies as the hours and days pass. There are many clues and many red herrings, and while we know Crystal’s story is also important because she’s the other narrator, we don’t know her role in the story.

While the beginning was a bit slow, the action and emotions really pick up once the baby is gone, and in fact, I stayed up late to finish the book and find out how it all ended. Frey has written a story that will chill readers but will make us think about living with a visual or hearing impairment. How do we remake our lives if we lose our sight? And the fact that Bec has also lost every single person in her family is perhaps the worst loss.

It’s not all dark, though. Frey provides a very satisfactory ending with a hopeful tone for Bec’s future. Light at the end is welcome, indeed.
