Mo Marley's side will congregate in separate groups for two training camps at St. George's Park this week.
Flint has been selected in the first squad who gather on 29 January and the second group, including Brooks, will meet on 31 January. Both groups will play a friendly against Norway.
The camps will allow Marley to monitor the squad of 42, before she picks the team who will participate in the European qualifiers. England lock horns with Denmark, Serbia and Finland in April, with the winner of Group Six securing qualification for this summer’s finals in Norway.
England reached the final of last season’s tournament but lost to France after extra-time.
