This title introduces two space adventure novels in the popular ''Liaden Universe'' series in one popularly-priced Omni-trade edition: ''Agent of Change'' and ''Carpe Diem''. ''Agent of Change'': Once a brilliant First-in-Scout, Val Con yos'Phelium was 'recruited' by the shadowy Liaden Department of Interior and brainwashed into an Agent of Change - a ruthless covert operative who kills without remorse. Val Con has been playing a deep game, far from the orderly life of clan and kin. Fleeing his latest mission, he saves the life of ex-mercenary Miri Robertson, a Terran on the run from interplanetary assassins. Thrown together by circumstances, Val Con and Miri struggle to elude their enemies and stay alive without killing each other-or surrendering to the unexpected passion that flares between them. ''Carpe Diem'': On the run from interplanetary assassins and a ruthless interstellar crime cartel, covert operative Val Con yos'Phelium and former mercenary sergeant Miri Robertson formed an alliance of necessity and wound up stranded on a planet with no rescue in sight.Their on-world problems were looking manageable after they assumed new identities as musicians, that is until a local war forced them to reveal their alien combat skills - and doubt their own growing partnership of trust and love.
