Are there any good sci-fi novels about aliens invading Earth?

They’re big, they’re blue, and they’re taking earthling females as mates. Alien Mate 1: Diana is ironing her underwear when the hottest blue babe in the galaxy appears in her living room—naked. Abducted, decontaminated and dressed like a harem girl, she’s been chosen to become the alien’s mate. Alien Mate 2: Maya's been raised to believe in extra-terrestrials and when she saves a sexy blue one from drowning, she can't resist taking him home-and into her bed. Alien Mate 3: Abducted by a hunky blue alien, researcher and admitted geek Penny is eager to study his mating habits—in the flesh. She’d like to blame her illogical affection for him on hormones, but the erotic remedy just heightens her chemical imbalance. From the sands of white Mexico, to the Xamian home planet, and the vast galaxy in between, three different tales of alien love with a large dose of humor and pleasurable probing. Alien Mate is created by Eve Langlais, an eGlobal Creative Publishing Signed Author.
