They include some familiar names, including three who faced England in that memorable World Cup final in Paris in 2014, the captain Laura Russell, Tyson Beukeboom and Elissa Alarie.
Of the XV that started against the Red Roses in Doncaster last November twelve are retained: Russell, DeMerchant, Menin, Beukeboom, Holtkamp, Senft, Slevinsky, Miller, Holly, Tessier, Alarie and Thibault. Menin will be familiar to English fans from her season with Loughborough Lightning.
Two distinguished faces are missing: Cindy Nelles, their powerful No 8, and Magali Harvey, their outstanding right winger. But De Goede should prove a more than adequate replacement for Nelles. She captained the Under 20 side against England U20s with authority.
The head coach, Sandro Fiorino has followed his French and New Zealand counterparts in posting a roster of 30. It will be interesting to see whether the two extra bodies in those three squads can make a practical difference to the results.
As Sarah Hunter has pertinently pointed out, this competition can claim to be even tougher than a full World Cup. Only here will a nation be faced with four opponents of such standing.
The first fixture takes place between Canada and New Zealand on Friday June 28
