I imagine it's pretty difficult to contrive a marriage of convenience plot in a contemporary romance without enlisting the services of crazy family members, especially if you don't want to keep going to the immigration well. I think Leigh Michaels did about the best she could - especially considering all the story beats she had to pack into a short novel.

Goethe could never disappoint me! Maybe at some point in his long life he will write something I don't love, but whatever that is is just a drop in the giant bucket of delight he's brought me. Look at this picture! Don't worry, Goethe! <3
