Okay I know this is completely random, but I've been thinking about the fact that several books that I've read recently have fundamental similarities even though they are about very different subjects. To tell you what I mean by this, I'm going to do a Six Degrees of Separation from Such a Rush by Jennifer Echols to Shadow of Night by Deborah Harkness. I've read (and enjoyed!) all of the related books in the past month.
NOTE: The similarities between these books aren't spoilers (okay one is a mild spoiler, but I'll tell you when you get to it - don't worry!), so it doesn't matter if you've read them or not.
Code Name Verity and Outlander by Diana Gabaldon both include Scots wearing kilts (I've grown to appreciate kilts a great deal after reading these books). Bonus: They also both have characters who were/are involved in the British war effort during WWII.
In Timepiece and The Golden Lily by Richelle Mead, the formerly stilted guy finally gets his chance at love (okay maybe this is a tad premature for Adrian, but I have high hopes for him and Sydney!)
The Golden Lily and Shadow of Night by Deborah Harkness both feature main characters that are vampires who can go outside in the daytime.
So there you have it. A small look at how my brain makes connections between books. Can you make your own six degrees out of the books you've read recently? See any connections I missed?
BONUS! All of these books are pretty Mild on the love triangle scale.
