Half Sister, The by Sandie Jones; 2020. Softcover.

Kate and Lauren meet

for Sunday lunch every week without fail, especially after the loss of

their father--but a knock at the door is about to change everything. A

young woman by the name of Jess holds a note with the results of a DNA

test, claiming to be their half sister. As the fallout starts, it's

clear that they are all hiding secrets, and perhaps this family isn't as

perfect as it appears.
