Echoes (en Inglés) - M. A. Colestock

Seymour Frankford Albatross has a problem: he might be an alien. Ted and Richard have a different problem: they hate their jobs. So does Jason. But humanity has a yet even bigger problem: impending destruction. As Ted and Richard divest themselves of their careers to leave planet Earth behind, an array of extraterrestrials, from Martians and Venusians to beings from beyond the comprehensible universe, use every method at their disposal to hijack the human race and steer it towards oblivion.
