James Yaffe’s series featuring official protagonist, Dave, and more importantly, Dave’s mom, Mom, is a really really fun series that has been out in e-book for a while, but insanely expensive. Now the second book in the series, Mom Meets Her Maker, has dropped to $3.99 in the US. Still not a great price for a book that came out in 1990, but it’s a fun fun series.
