The all-rounder enjoyed a breakthrough year in 2013, as she shone in her first taste of international cricket.
Sciver made her county debut for Surrey in 2010 and two years later was first selected for the England Women's Academy.
Sciver, a student of Sports and Exercise Sciences at Loughborough University, made her debut against Pakistan in the summer 2013 before going on to be named in the Ashes squad.
During the success against Australia, Sciver contributed 44 runs with the bat in her two one-day international appearances and 56 in the three Twenty20s.
She shone with the ball in the tour to the West Indies, taking a hat-trick against New Zealand as England booked their spot in the tri-series final.
