Error in book description

[Yvette]

I would like to signal an error in the book description of A court of Betrayal.

The description mentions:

Strong-willed heiress Joan de Geneville is married to Richard Mortimer, Earl of March, ....
Soon Joan finds herself swept up in a world of treacherous ....
Yet when Richard is accused of treason, she is robbed of her freedom ....


In the book, the main character is consistently named Johane, not Joan. This could be a difference between editions though I doubt it.
Furthermore, his name is not Richard but Roger.

Kindly have a look at this
