内容简介：
Ally and her sister couldn't be more different. While Ally is happily married to Luke, with four children and a cozy home life, Miranda is child-free, has a millionaire husband and lives in a show home that wouldn't be out of place in the pages of House and Garden. Ally gave up trying to compete years ago. But she is shocked when Miranda asks her if she'll help provide the one thing that is missing from her perfect life: a baby. Ally has every sympathy for Miranda's infertility problems, but can she really have a baby and hand it over to someone else? Especially if that someone else is Miranda...
