The Run Series by Jason Reynolds 4 Books Collection Set:

Ghost
Running. That's all Ghost (real name Castle Cranshaw) has ever known. But Ghost has been running for the wrong reasons -until he meets Coach, an ex-Olympic Medallist who sees something in Ghost: crazy natural talent. If Ghost can stay on track, literally and figuratively, he could be the best sprinter in the city. Can Ghost harness his raw talent for speed, or will his past finally catch up to him?

Patina
It's not the taking part, it's the winning that counts for Patina! Patty, as she's known to her friends and family, has lost a lot in her life - her dad died when she was young, her mum has lost her legs and now she has to live with her uncle and his wife. On top of that Patty has to go to the poshest school that ever existed. Now her running team has become a relay team and independent "I can do everything by myself" Patty has to work with her team mates to win.

Sunny
When Sunny stops running in the middle of a race, Coach asks him what he wants to do instead. His answer is dance, but you can’t be on a track team and dance… can you? With his dad’s expectations weighing down on him, Sunny finally finds a track event that feels like dancing. But as he practices for this new event, can he let go of everything that's been eating him up inside?

Lu
Lu was born to be co-captain of the Defenders. Well, actually, he was born albino, but that’s got nothing to do with being a track star. Lu has swagger, plus the talent to back it up, and no-one’s gonna outshine him. Lu knows he can lead Ghost, Patina, Sunny, and the team to victory at the championships, but it might not be as easy as it seems. Suddenly, there are hurdles in Lu’s way - literally and not-so-literally - and Lu needs to figure out, fast, what winning the gold really means
