I haven't read the book, but it seems it is kind of an "individual" work of the author, his own thoughts on Epicurus. Springer is a reputable publisher. The author has his own wikipedia entry.
At a glance, the author seems to summarize contents which seem to be already known to ordinary students of Epicurus. The table of contents features current political issues he discusses in relation to Epicureanism.
