Only Make-Believe — Julia Winfield

When Darcy Stevens hears that the students in her social studies class will be paired off in mock marriages, she assumes her "husband" will be longtime boyfriend Bruce. But instead she's matched up with quiet, bookish Josh Foster. Suddenly, the semester ahead looks very dull.

As she gets to know Josh, Darcy discovers that she honestly likes him. He's funny, kind, smart - the things she most admires in a boy. But what about Bruce? she wonders. Will her growing attraction to Josh tear them apart, or can Darcy convince Bruce - and herself - that her new feelings are only make-believe?
