Upside
- The prelude is pretty entertaining and exemplifies the general attitude of many young Lasombra
- The clan's history is delivered in sessions narrated by various Lasombra (concluded by a Lasombra antitribu's suicide note, strangely enough)
- Details how the majority of Lasombra go about observing, testing and training recruits
- Briefly desribes Lasombra culture and its many, many unofficial "factions" as well as official ones and the supposedly non-existant Lasombra antitribu
- The basic break-down of procedures for dealing with the Courts of Blood is rather helpful
- The Lasombra's comments on the Sabbat bloodlines and the other clans are more informed than average (but, perhaps unsurprisingly, there's nothing of consenquence said about the Kiasyd)
- Takes a closer look at the basic Obtenebration powers and provides more advanced ones as well as interesting suggestions of ways to approach peculiarities of a Lasombra's manifestation of Obtenebration
- Explains a little about the occult and Abyss mysticism
- There are actually a few appealing Merits and Flaws (Controllable Night Sight, Death's Reflection)
- There are several pseudo-templates of variations of the Path of Night as it's presented in the core rulebook and some of them look like they'd be very interesting to adopt
- There are some great character templates (the Accuser, Angry Young Man, Successful Mass-Embracee, Harpy, Student of the Abyss)
- The sample brood of mentally-unbalanced Lasombra computer hackers is quite interesting
Downside
- There's relatively not that many notable Lasombra mentioned
- The book's formatting oversights do not make finding specific entries any easier
