Taking my answer from my wild guess in the comments above, the series is The Seems. A fun read, even if you're an adult.
The series follows Becker Drane, a Fixer for a world called The Seems, which provides our world with resources such as Sleep, Time and Energy.
In the first book, Becker Drane must find and capture a Glitch wreaking havoc in the Department of Sleep. Glitches are creatures with three arms that are able to move very quickly, creating problems wherever they go. With the help of Briefer Simly Frye and Fixer Casey Lake, the three try to Fix this Glitch. After many challenges, Becker manages to find and capture the Glitch.
In the second book, The Tide, using 50 trays of Frozen Moments, has managed to construct a Time Bomb which could cause unimaginable damage to both The World and The Seems. The Fixers are not able prevent the explosion, and Essence is spilled into the World. Becker Drane, Fixer #37, is sent in to recover the bomb, which could still be hazardous. Tom Jackal, Fixer #7, who was thought to be dead, Fixes the bomb but dies in the process. Becker also breaks the Golden Rule, which forbids anyone with access to a Case File for a person in The World to have contact with that person.
In the third book, Becker is found guilty of breaking the Golden Rule by meeting with Jennifer Kaley at the end of The Split Second. Because of this, he is suspended from duty for a year, and his memories of Jennifer are "unremembered". Jennifer is also unremembered of everything about The Seems. However, before they are both unremembered, a train of Thought goes missing and Becker is called in with three other Fixers to find it. The train is found, and Becker must drive it back. However, all the extra Thought that The Seems had was spent already. To get The World the Thought it needs, Becker drives through to the Inbetweener. He succeeds in getting the Thought back, but he crashes into the dangerously low entrance and may not have survived. Jennifer receives a job in The Seems, but at Becker's request, she is still unremembered about Becker and The Seems.
A fourth book, titled A Better Place, has been confirmed on the official website for the series. "Chapter Zero" of the book was made available to read in May 2012, but as of July 2015, no release date or cover have been revealed. However, as of May 2015, the authors have continued to indicate that they are working on getting it released eventually.
