Please help me with my vertical leap issues. skinny.fast metabolism.15years old. 6''2?

i need a workout for my vertical leap now that my bball season is over. i wasnt the best on my team. i only average 2 points and like 2 blocks a game. im not a starter for alot of reasons, one of them because of my skinniness and my poor rebounding. everybody on the team keeps on telling me to'' eat food!'' and ''get big!'' i do try to eat a lot of food too. so any workouts for improving my vertical leap? btw i can touch the 10 foot goal when i do a running jump. and i want to be able to dunk it by next say... october-november. and i am dedicating my summer to basketball.(i have my own net...) and i hope to god that i grow more this summer! thanks in advance! BTW im kind of built in the shoulder, chest and ab area but i want to focus on serious leg training and abs. btw for until june i have a leg press ,calf thing (i forget)!, squats, dumbells and leg extension. then in the summer its at home workout. with no weights.
