James Patterson 
First Love 

When Axi Moore decides to take a road trip across the US, the only person she wants to go with her is her best friend Robinson – who she also happens to be secretly in love with. She’s planned it all out, and all he has to do is say yes.
Axi has had a tough life: her little sister died young, her mother walked out and her father turned to the bottle for comfort. Her parents escaped their grief in their own ways; this trip will be hers.
But life doesn’t always work out as you plan it, and there are some things you just can’t run away from.
