That Could Be Enough by Alyssa Cole 

Mercy Alston knows the best thing to do with pesky feelings like “love” and “hope”: avoid them at all cost. Serving as a maid to Eliza Hamilton, and an assistant in the woman’s stubborn desire to preserve her late husband’s legacy, has driven that point home for Mercy—as have her own previous heartbreaks.

When Andromeda Stiel shows up at Hamilton Grange for an interview in her grandfather’s stead, Mercy’s resolution to live a quiet, pain-free life is tested by the beautiful, flirtatious, and entirely overwhelming dressmaker.
