Dear Ludovico,
Thanks for your interest. The "Ace of Hearts" Squadron history is Hungarian language only (the English edition is depends on the foreign publishers, as always) However, I guess, the Hungarian version will be the sweetheart of many foreign biplane fans as well (where is Hĺkan?

)
By the way, it contains few interesting details about Italian flyers as well (from Krivoy Rog area)
I have no info about the Baptism of Fire (that project suffered a lot of delays and some details are still hazy to me)
