This book is not a sequel to What Heals the Heart. (BTW, that book is available on Kindle Unlimited, for those who have access to it.) Rather, as with many romance series, it returns to the same locale -- Cowbird Creek, in this case -- and shifts the focus to other characters. Tom and Jenny both appear in the first book, but now take center stage. Those who've read the first book will see the reappearance of its main characters, Joshua and Clara, as well as important secondary characters like Freida, Jedidiah, and Madam Mamie. And you'll get to know some other characters, like Silas Finch, rather better.
Without further ado, here's the final excerpt, in which Jenny asks Madam Mamie about whether she's seen any girls "in the life" who got married, and Mamie tells her what happened to some who did.
