Flowing Streams -- Catholic Bible Study... by a veteran homeschool mom of eight whom I know from her wise posts online and sort of know in real life (I met her grown son and his wife once, they are expecting their third soon!) Anyway, the bible study is thoroughly based in Catholic exegesis methods and very substantial, plus the visual arrangement is beautiful.
Amazon's Limited Time Kindle freebie page -- I check here often, there is lots of junk but you sometimes find something good and sometimes "limited time" is only a couple of days or so, so it pays to check!
