Two best friends, a tipsy Oktoberfest dare and one kiss that could change everything.

It's been fifteen years since big-shot marketing manager Fi first met her bi best friend Max. Living on different continents has had its challenges, but she's determined that their friendship will be as strong as ever when she arrives in Munich for an Oktoberfest reunion with their study abroad friends. There's no one she loves like her Max, even if he has finally grown up a bit and now runs a microbrewery.

But instead of lazy conversations and comfortable day-drinking, as they'd always done when they were younger, the reunion is a slightly desperate meeting of disillusioned millennials escaping real life - until Fi's jetlagged, drunken rant about being a woman working in beer marketing goes viral and they're roped into a bad-taste beerfest challenge. As she and Max and their friends from the international dorm tackle fairground stunts, physical challenges and bad karaoke, the one dare that changes everything is the simplest: kiss your teammate.

Now she can't stop thinking about him in a very more-than-friends kind of way. When kissing leads to more and she discovers that her screwball best friend can talk dirty and light the sheets on fire in the bedroom, she can't help seeing the years of their friendship in a new - and terrifying - light.

As the challenge progresses with thrill rides, pretzels, lots of lederhosen and a little public nudity, the dares are actually fun, when Fi completes them on her own terms. But the truth questions present the biggest danger to her future. What happens to her precious friendship - and her big promotion - when she admits to herself just how much Max means to her?

A spicy romcom with a bit of snark and a lot of swoon, for fans of Helen Hoang and Christina Lauren.
