England Under-23 international Melissa Lawley will join Manchester City Women in January.
The 22-year-old has signed for the Super League champions, bolstering Nick Cushing's attacking options.
Creative, with pace and flair, Lawley hopes to develop her talent and progress her international career.
Lawley signed for Birmingham in 2013 from Bristol Academy. Born in Kidderminster, she began her career with Arsenal and gained valuable Champions League experience.
The forward has faced her new Club six times for Birmingham, and liked what she saw from the opposition. Now, she is relishing the competition that accompanies joining the reigning double champions.
