Books like It must have been the mistletoe by Moyra Tarling

Abby loves the chocolate of Valentine's Day but not the mushy sentiment. When someone misreads her feelings, a heartwarming friendship lesson unfolds.

When Evan Nazarenus returns from a teaching post at the summer school in Nebraska, he cannot wait for a couple of blissful weeks spent with his wife and two children in Clovis, a small town where his brother has a summer house. But soon after they arrive for the long awaited holiday, Swan, Evan's wife, announces that she is expecting a child … who is not fathered by Evan. This news shocks and hurts Evan deeply, but for his children's sake he decides to keep it to himself through the holidays they dreamt of for so long. But a family secret of such caliber is difficult to hide and the curious small-town neighbors begin to notice that something is amiss with the couple. The Laughing Matter, first published in 1953, is a disturbing family drama set against the landscape of a small Californian town, with a close-knit community who embrace new-comers with the curiosity of those hungry for gossip. William Saroyan draws his characters with immense sensitivity for human erring and self-inflicted suffering.

When a lonely holiday season forces her to pose as a couple, formerly broken-hearted Elise learns that easing into love may be more fragile than truth itself.

Abby is a children's mystery series by Pamela Walls that blends detective adventure with Christian values, exploring themes of faith, community, and courage.
