A cool million to help a withdrawn child in time for kindergarten? Widowed teacher Ava Barton is touched that the girl's guardian, Texas billionaire Will Delaney, cares so deeply. But the job includes moving into Will's mansion for the summer. And suddenly, Ava is working nights and weekends trying -- unsuccessfully -- to resist the gorgeous tycoon down the hall. Will wants her in his bed for June, July and August. But come fall, he'll move on. Unless she can teach him a thing or two about opening his guarded heart to love.
