I'm not going to lie, this volume of Runaways is definitely stressful and sad, but it's more than worth reading and will probably intensify your love for some characters, or get you to like them in the first place if you didn't before.

Members of the group who weren't previously given the time to really explain their emotional and personal mindsets finally got their hour in the sun, amounting to some of the most important and powerful moments in the series. 

These issues are probably the one with the most growth and depth so far, and also contains a plot that held my attention the entire way through. If the comics only go downhill from here I won't even be mad.
