Acorna's Triumph (Acorna series, 7) by Scarborough, Elizabeth A.. mass_market edition. ISBN: 9780380818488.

Aari has returned! Now he and his lifemate, the brave and beautiful Acorna, can finish rebuilding their once-decimated homeworld. Yet Aaris travels through time have left him oddly changed, and he barely remembers Acorna or their love. And as Aaris actions turn more sinister, Acorna must shift her attention to stopping the destruction of innocents by a vicious criminal. It is precisely the sort of weakness and confusion the dreaded Khleevi have been hoping for, as the brutal insectile oppressors set in motion their final invasion and the total destruction of the Linyaari and the conquest of their world. Though Acornas heart is wounded, her courage and determination must remain strong in this dark time -- for only then will she be able to rescue the Aari she knows and adores, and halt the bloodthirsty alien menace for good and for all.
