The trouble with authors and series that you love is that the books are never long enough (or released often enough) for my liking. So it is with the Immortal Descendants.
Simon and Elizabeth's previous activities (bringing Jack out of his time) have altered the fabric of time - this has had knock on effects which has resulted in the great physicist Niels Bohr being put in danger. Simon and Elizabeth have been sent back to 1912 to keep him safe.
Almost immediately Simon and Elizabeth run into a sinister looking German-speaking man who seems to be following Niels. When Niels boards the Titanic things gets serious.
I always think of the Immortal Descendants being in the same vein as the idealistic fiction of the 1930s-1950s - the Captain America type genre, or even Lord Peter Wimsey. Simon is British, his full name is Sir Simon Cross and he is fabulously wealthy. Elizabeth on the other hand is American, younger and far more idealistic. Her motto seems to be 'Because it's the right thing to do'.
Here while Elizabeth tails suspicious Germans, breaks into first class cabins and makes friends with other passengers, stowaways and the crew and generally has the sort of fun that only the Famous Five used to have (or perhaps the Secret Seven), Simon wrestles with his fears for her life as they steam towards the historical iceberg. Here we have Russians who look like bears, superior-acting French people, jingoistic Americans and more.
I just love it, love every book in the series and love Simon and Elizabeth. Yes I guessed the identity of the spy, yes I spotted other clues but I don't care because I L.O.V.E.D. it. It's time travel, what's not to love?
Recommended for anyone who loves light-hearted husband and wife detecting duos, historical settings and plots involving Europe on the brink of World War One.
