The first in a brand-new sensationally spacey, action-packed and adventure-filled middle grade series written by the incredible Lorraine Gregory - perfect for fans of MG Leonard and David Baddiel! Nothing exciting ever happens on twelve-year-old Danny's estate. That is until he falls through a locker in his grandad's workshop and finds himself in an Interdimensional Lost Property Office! And - even weirder - his new boss is a giant purple squid on a segway! Now Danny, best mate Modge and annoying cousin Inaaya find themselves in charge of returning alien items to all corners of the universe. But someone - or something - is determined to stop them.

And there's NOTHING these evil aliens won't stop at to achieve complete multi-dimensional domination . . . even trapping Danny and his friends on a planet a million light years away from Earth. If the fate of the entire multiverse was in your hands, what would YOU do?
