The South East Stars seamer represented England Women A in their tour to New Zealand in March and will link up with the squad in Durham later today.
Heather Knight鈥檚 side begin their Metro bank ODI series against the White Ferns at the Seat Unique Riverside tomorrow lunchtime.
Head coach Jon Lewis said: 鈥淩yana has been a standout bowler in domestic 50-over cricket and had a good 50-over tour of New Zealand with our England A team.
鈥淲e have brought her in at this point as we have a couple of niggles in the squad. We have been really impressed with her skill level and accuracy.
鈥淪he is an exciting young talent and we look forward to having her in the squad.鈥�
