Daisy Kirkwood has only just escaped her small-town life and run away to New York City, the land of last-minute secret gigs at famous musical venues, when she's kidnapped by aliens. Unfortunately, no one ever writes about how to handle alien abduction in those fancy NYC guidebooks. Griffin and Dev are supermassively sexy aliens from a politically and environmentally troubled planet who arrive on Earth with very little knowledge about human ways other than what they learned from a wayward E! News signal. Their mission is to pretend to be the most influential people on the planet—English pop stars, of course!—and gain the help of a powerful secret society. Upon arriving, they abduct Daisy Kirkwood, a nerdy young woman who loves music but could seriously use a bit of help in the love-life department. Though Griffin and Daisy initially squabble, neither can deny the intergalactic sparks whenever they're too close to each other. Together, they must face murderous aliens, cultural misunderstandings, bad backup musicians, and the dark side of fame and the media, all set against a tight deadline… Part High Fidelity, part Bridget Jones' Diary, part Doctor Who, Dating an Alien Pop Star is a sexy romantic comedy.

Daisy Kirkwood and her best friend Kammie have adjusted to life on an alien planet pretty well, all things considered. And thanks to Daisy's alien pop star boyfriend, Griffin Valentino, she has plenty of sexy new experiences to keep her busy. But it's not possible to take a massive music nerd away from her home planet and not expect her to pine for a concert or a record store at least in once in a while. Heading back to Earth with Griffin and his best friend Dev for a brief but much-needed visit, the girls want nothing more than to catch up on the underground music scene of New York City. Unfortunately, thanks to Griffin's less-than-stellar space traveling skills, they accidentally pick up a hitchhiker. Or three hundred. Their many-legged stowaway beasties take up residence in the darkest, creepiest corners of Manhattan, leaving the gang no choice but to experience a very different underground than they bargained for. Giant alien bugs aside, Griffin has some epic plans of his own for their trip, plans that involve a concert, an album… and the most outrageous marriage proposal that Earth has ever seen.

Daisy and her alien fiancé Griffin are planning a big wedding, but not just any big wedding – the biggest wedding the universe has ever seen. Daisy has been settling into life on Griffin's home world of Kalesstria, running her own intergalactic music shop and planning for the big day. But things hit a road bump when there’s a problem with Griffin’s father – and it’s a little more complicated than the usual disapproving dad drama. Looks like “save the date” is going to have to take a backseat to saving the universe… Marrying an Alien Pop Star is the perfect laugh-out-loud romantic finale to the beloved Alien Pop Star series.
