Fun question;-)
Angie is right, Inge is a Dutch name (possibly derived from the Scandinavian/Swedish Inga).
You pronounce it as ing-e (the end 'e' sounds more like the 'e' in the word 'the' than as an a). The 'g' is almost silent, although there's the smallest trace left, like in the word 'amazingly' and then you quickly add the 'e').
Usually English-speaking people find it difficult to pronounce, often they do pronounce the 'g', but they make it into a 'hard g', as in the word 'gossip'.
Hope this doesn't sound too complicated;-)
Lise is pronounced: lee-ze (second 'e' sounds the same as in my name). Mia was close, because there is another, very similar, Dutch girl's name: Lies, and then you would indeed say LEES.
Aaaah, names and languages, and the differences between them, they never stop to intrigue me (call me a geek, but I'm really interested in all that stuff;-)
By the way, what is the title of the book Mia is reading Nicole?
