What Are Best Friends For? More than anything, Summer Patterson wants a baby. What she doesn't want is a husband. Thankfully, her best friend, Ryder McClain, makes the perfect sperm donor. Ryder is loyal, undeniably sexy and the one man she trusts-- the only reason she agrees to conceive their baby naturally. When baby-making nights with Summer blaze like the West Texas sun, Ryder feels the heat. He never expected Summer to say yes to sharing his bed. Now he's falling for her-- and the prospect of fatherhood-- while hiding a secret that could destroy her faith in him forever.
