By Proxy is a debut novel by Katy Regnery. Ingrid and Kristian want to get married as they have a baby on the way but can’t get married in person because they are serving overseas in different places. They asked their two favourite people, Jenny and Sam, to act as proxies for them in Montana which allows proxy marriages. A snow storm delays Sam so he and Jenny miss their appointment. Not wanting to disappoint Ingrid and Kristian, they decide to try again on Monday. Over the course of weekend he and Jenny start to fall in love.
