Trail of Broken Wings

It was a Kindle first, if I'm not mistaken, and the storyline seemed really involving: three sisters reunited for the imminent demise of the father, who was in a coma. As the story started, it revealed more nuances of them and the mother as well as the fact he was an abusive violent husbNd and father, and the conflicts start to arise. I am not even sure the characters were amazingly developed, but the feelings and issues were real and so sad I couldn't help but empathize - sure sign of well told story, right? also, the same goes for the ending: even with a couple of twists and hollywood like surprises and happy endings, I could only think that “happy” would always be in progressfor such people.
I'm deeply sorry for everyone who had to live with an abusive family member. Scars must be deep.
