Now that her cousin has tied the knot, Iris Chin—structural engineer, party girl, and queen of kitchen disasters—is the last single grandchild. Her mother and grandmother are desperate to play matchmaker, though Iris doesn't understand why. They had miserable marriages, and she doesn't want to be like them.

But more than anything, it's her unwanted feelings for Alex that are derailing her plans to have an exciting single life...
