|Vanessa Blé will have her first stint outside of Spain when she steps out for Galatasaray|
Christon is the first American signing for BLMA who are returning to the competition after a season's absence playing in EuroCup Women.
The 31-year-old swingman has played three successive seasons in EuroLeague Women where she showcased her three-point threat and scoring prowess, playing a campaign with Lotos Gdynia either side of two separate stints with Nadezhda - the last of which was during 2010-11.
Most recently, Christon stepped out in the WNBA with San Antonio Silver Stars.
Ble meanwhile has been added by Galatasaray as a temporary replacement for EuroBasket Women 2013 MVP Sancho Lyttle, who is struggling to recover from a troublesome foot injury.
The Spaniard had initially been expected to had reached an agreement with another Turkish club in Tarsus, but will instead head to Istanbul.
Ble helped Spain to qualify for EuroBasket Women last summer, but did not make it onto the final roster which stepped out in France.
