On February 1, a woman contracted with a famous landscaper to drastically change the sprawling front lawn of her mansion. The woman had long admired the landscaper's work. The landscaper promised to complete the work before April 30, the date of the woman's annual spring party. On March 1, the woman left for a month's vacation. After beginning the work on the woman's lawn, the landscaper became increasingly anxious about finishing other prior commitments and assigned the contract to a local lawn care professional. When the woman returned, she was horrified to find the lawn care professional shaping the hedges on the front lawn. The woman contacted the landscaper, and he informed her of the assignment to the lawn care professional and told her that he was no longer obligated under their original contract. Although the landscaping project was coming along nicely, the woman fired the landscaper anyway. If the woman asserts a claim against the landscaper based on breach of contract, what effect will the fact that the landscaper assigned the contract to the lawn care professional have?
