Adam Mansbach famously gave voice to two of parenting's primal struggles in Go the F--k to Sleep and You Have to F--king Eat - the often-imitated, never-duplicated pair of New York Times best sellers that ushered in a new era of radical honesty in humor books for parents. But what could possibly be left?

Parents - new, old, expectant, and grand - of multiple children already knew the answer. Author Adam Mansbach discovered it for himself by having two more kids, less than two years apart. F--k, Now There Are Two of You is a loving monologue about that new addition to the family, addressed to a big sibling and shot through with Adam's trademark profane truth-telling. Chock-full of unspoken sentiments channeled directly from the brains of parents worldwide, F--k, Now There Are Two of You articulates all the fears and frustrations attendant to the simple, math-defying fact that two is a million more kids than one. As you probably know by now, you shouldn't let a child listen to it.
