BiblioJunkies' Shel on Triumph of Death: modern day Hardy Boys with high tech gadgets and vampires

We have a great new review of THE TRIUMPH OF DEATH from our old friends at Bibliojunkies. Shel writes:

This third installment of ALEX VAN HELSING has Alex and a mysterious new friend, Astrid, trying to stop the “Triumph of Death” a spell which would create darkness and allow vampires to essentially take over the world...

As with the rest of the series, The Triumph of Death was fast-paced action-adventure and completely irresistible.  Alex is such a lovable character and the world created by Henderson is so much fun.  Probably the most mature 14 year old I can think of Alex's adventures are great for all ages.  I've recommended this series to people from age 6 to adults in their 50s and 60s.  Whenever I recommend the AVH series to someone, I tell them to think of modern day Hardy Boys with high tech gadgets and vampires.
I know the book description says that this is the final installment in the series, but I really hope that isn’t so.  I would hate to say goodbye to Alex and friends!   I have been thinking all day that I cannot be the only person who thinks AVH would make a great movie or tv series...

Hardy Boys. See that? It's like she read my mind. That's what I really want to do here, adventure stories like I used to read. Personally, I love wide-open series like REACHER and Cornwell's Kay Scarpetta, and that was what I've tried to emulate-- a world where instead of one epic story for the characters, you have a set of characters who conceivably can go on forever.
