An Amish Second Chance 

Newly widowed Lizbeth Mullet has a secret: she's never told anyone the true identity of her son's father. Not even now that she's come home to Pinecraft and the man in question is her new landlord. Fredrik Lapp may not know Benuel is his son, but the two soon form an unmistakable bond. And seeing Fredrik again stirs feelings Lizbeth had worked hard to bury. With Fredrick's affections resurfacing, too, the burden of Lizbeth's secret is only getting heavier. Revealing the truth could mean a lifetime of happiness together—or the loss of her second chance at forever.
