Ben has a problem. His home is his castle — literally, given it's a fortress floating in the clouds — and it's been invaded. By humans. And though he's a giant, a human infestation is nothing he wants to be a part of. So his only real choice is call up an exterminator and hope that they have a non-violent way of clearing out his home of unwanted guests.
What he's not expecting is for the exterminator to be ... so very hot. Drake is funny, kind, and gentle when it comes to Ben and his delicate sensibilities. But the humans prove to be a bit more persistent than either of them anticipated, and with Ben and Drake's flirting becoming more serious, shy and awkward Ben's problems seem giant indeed.
