Rachel Cooper has life under control: good job, good friends, and good plans for the future. All of that collapses one early morning when she falls and breaks her ankle. Now she must face the horrors of preparing for an upcoming move and handling her tenth year of teaching while clomping around on crutches. Worse, somewhere in the shadows, the Memento Killer lurks—a serial murderer who stalks women with four anonymous gifts before moving in for the kill. When unexpected presents begin arriving on Rachel's doorstep, she fears that she'll soon be crutching for her life. Collapsible. A novel of friendship, broken bones, coffee, shenanigans, and the occasional murder.
