Super Powereds by Drew Hayes.

Supers : People with powers.

Powereds : People with powers they have little/no control over. One you meet in passing is a man who teleports to a random location whenever they sneeze. Other than not being in any immediate physical danger they can appear anywhere. The only control they have is they carry a feather. To force a teleport if they're in danger. One of the main characters floats whenever they get happy.

Anyway, one of the main characters has the power of luck. Very bipolar, one instance had him winning money, then getting hit by a car (IIRC).

In the books, the main characters undergo a procedure to move them from Powereds to Supers. The luck guy starts out very reluctant to use their power but learns to trust it more.

From the amazon page of book one:

>Knowledge is power. That would be the motto of Lander University, had it not been snatched up and used to death by others long before the school was founded. For while Lander offers a full range of courses to nearly all students, it also offers a small number of specialty classes to a very select few. Lander is home to the Hero Certification Program, a curriculum designed to develop student with superhuman capabilities, commonly known as Supers, into official Heroes.

>Five of this year’s freshmen are extra special. They have a secret aside from their abilities, one that they must guard from even their classmates. Because for every one person in the world with abilities they can control, there are three who lack such skill. These lesser super beings, Powereds as they are called, have always been treated as burdens and second class citizens. Though there has been ample research in the area, no one has ever succeeded in turning a Powered into a regular human, let alone a Super.

>That is, until now…
