Await Your Reply is ultimately a tragic story featuring characters who are lost or mentally ill and either want a new start or can't let go of the past. However, I found it hard to sympathize with the three characters whose perspectives the novel shifts between in alternating chapters. As a result I rushed through my reading mostly to finish the book and see how these seemingly unconnected characters were, in fact, connected. It's a story of identity, how it is mutable but perhaps can become its own trap, even when that identity is traded in for a new one.
I'm surprised I purchased this book since it features one of my greatest squicks (as we say in fandom): a teacher-student romantic relationship. The recently graduated student, Lucy, is one of the characters whose point of view is narrated. Though she's lost her parents, at first it seems this is not a great loss to her. She also disparages her older, less ambitious sister. This made Lucy and her rash decision to run off with her AP History teacher unsympathetic for me. She's bright academically, but stupid and naive when it comes to everything else. She almost immediately begins to feel uneasy about the promises her older boyfriend made once they arrive at their temporary destination, but she sticks around.
Similarly, Ryan, a college student, leaves school and his family behind once he learns the truth about his parentage. He hadn't been doing well in school and wasted the money meant for tuition. He takes off with a guy he's just met and becomes involved in illegal money-moving and identity fraud schemes, though he barely understands what he's doing and why. He doesn't seem that troubled knowing that his family is looking for him. So, he's another character I found I couldn't care about.
The third character, Miles, I found the most sympathetic. He's been on the trail of his schizophrenic twin brother, Hayden, ever since the latter disappeared years before. Miles disrupts his own life (or barely develops one) to chase his twin and feeds on occasional communications from him. He gives Hayden the benefit of the doubt, despite the warnings of others and evidence to the contrary. Is he big-hearted or a fool?
I won't spoil how the three characters' stories connect, but despite some surprises, the mystery of that connection wasn't enough for me to overcome my issues with the characters.
