Last Wish by Valerie Howard

Miranda Lewis doesn’t have time for cancer. Not when she’s filling out her Ivy League college application, competing with her boyfriend for the title of class Valedictorian, and counseling emotionally unstable underclassmen at all hours of the night. But medical tests don’t lie. A deadly tumor is taking over her brain, threatening to shatter her hard-earned dreams to dust.
Homework competes with plans for treatment, and Miranda’s stress only increases when her well-meaning parents schedule the local pastor’s kid to come over and pray for her healing every morning before school.
When Miranda learns her health is even worse than the doctor’s originally thought, she decides to look into religious matters, including life after death. Just in case. But placing her trust in an invisible God is harder than it seems, and when she lands in the hospital on the most important night of her senior year, her worst fears are realized. Where should she place her faith now? She must choose wisely. Before it’s too late.
Austin Reed is a slacker who barely squeaked through high school graduation last year. Working in a boring bait and tackle shop when he hates everything about fishing, he’s sure his worthless life will never go anywhere.
Then his dad gets the bright idea to volunteer Austin to pray for a girl who has a brain tumor. Unable to get out of the uncomfortable assignment, Austin puts as little time and energy into his dad’s request as possible. But when Austin learns Miranda’s health is worsening, he knows he’s to blame for his lack of faith. He promises to step up his game and help Miranda on her quest to find the answers to her pressing religious questions.
Just when things seem to be headed in the right direction, Miranda collapses on the night of the senior dance. As her life hangs in the balance, Austin has to decide once and for all how he’s going to make his mark on the world.
