I'm almost finished with Legends and Lattes and most of the book is low-stakes. Plus, the serious parts aren't presented in a heavy way. For example, >!Viv is depressed about the fire for two days and then conveniently everyone pulls together to rebuild despite the fact that there's no money for it.!<

I find false advertisement more common in literary fiction, where the person who wrote the summary tries to invent a plot or raise stakes that're not actually there. For example, I just read We Measure the Earth with Our Bodies by Tsering Yangzom Lama. Part of the description is:

>When Dolma comes across the Nameless Saint in a collector's vault, she must decide what she is willing to do for her community, even if it means risking her dreams.

This is really not what happens at all.
