Special Master Books still going on?

I remember a week or two ago when I leveled my Aran to 70 I got a popup from the Maple Admin saying I could choose some 4th job, tradeable, instant level 30 master books. I got AFA 30, but that's not what I'm trying to ask. My question(s) are:

1. Is the "event" still going on?

2. What classes are eligible for the event? (more specifically can Mercedes get the popup at level 70)

Any help is appreciated as I cannot find any information about this. :\
