Another book in my wishlist is The End of Forever by Lurlene McDaniel. The part of the glimpse that i've read that caught my eye was :

"Lurlene McDaniel explores the complexities not only of accepting unexpected
loss, but also of moving on to live and love again."

I'll let you read the whole preview so that just maybe, it would interest you to purchase a copy.

For sisters Amy and Erin, the night of their high school drama group’s cast party starts out as fun.

But their lives come crashing down when Amy takes the car to get more food and has a horrible accident. Now Amy lies somewhere between life and death.

Erin and her parents must find the courage to accept Amy’s life-support system will never bring her back. Can Amy’s dying become hope for someone else’s living?

The doctors assure Erin Bennett and her parents that they can’t find a physical cause for her headaches. But the throbbing, violent pain is so intense that Erin knows she needs help. Even landing the lead in the senior musical opposite David Devlin doesn’t give her much pleasure.

The headaches started just after the death of Erin’s younger sister, Amy. Erin thought her grieving was over. A therapist begins to help her deal with her pain, but what is it about David that triggers Erin’s violent reaction?

In these companion novels, now together in one volume, Lurlene McDaniel explores the complexities not only of accepting unexpected loss, but also of moving on to live and love again.
