I've only recently started to read the Vanguard series. I'd picked up Harbinger on a whim several years back, read it, and didn't find it all that compelling. It sat on the bookcase ever since. Recently, I started to search for some new series to read. I thought about Vanguard again. The fan reaction to the series has been so overwhelmingly positive that I thought I should give it another shot. I re-read Harbinger and enjoyed it much more the second time around. I've just started Summon the Thunder and I already have a copy of Reap the Whirlwind on deck to read next. News of the series ending makes me sad. However, it's encouraging to know that the series will come to a natural, carefully-planned conclusion rather than just stopping abruptly or fading away without resolving the main story threads. I also can take solace is knowing that I've got several books to go before I reach the end.
